Conversation
📝 WalkthroughWalkthroughThe change adds composed-schema union handling to generated models and expands notification channel support to SMTP, default SMTP, and in-platform destinations. It also adds public exports and regression tests for model and destination serialization. ChangesComposed model union support
Notification destination support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change broadens generated composed-model support, but nested composed variants can still be rejected and the new test fixtures have a reported lint issue. Merge should wait for these bounded correctness and validation concerns to be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

`CatalogLlmProvider.to_api()` raised `ApiValueError: Invalid value for
`type` (AZURE_FOUNDRY), must be one of ['OPENAI']` for every LLM provider
except one, so `create_llm_provider()` / `update_llm_provider()` were
unusable for OpenAI, AWS Bedrock and Azure Foundry alike (reported against
1.73.0, where the one that worked was Anthropic).
openapi-generator's `python-prior` generator flattens a oneOf's members
into the composed parent model, but for a property that several members
declare it keeps only the *last* member's value. Two things collapse:
* `allowed_values[('type',)]` holds one member's enum, so the parent
accepts exactly one variant - and which one depends on the order of
the oneOf array in the OpenAPI document. That is why the released
1.73.0 accepted only ANTHROPIC while master accepted only OPENAI:
the backend had reordered the array, nothing else changed.
* `openapi_types[prop]` holds one member's class, so the *nested*
`auth` union could not carry Bedrock or Azure Foundry auth either.
Fixed in the custom templates so it survives regeneration, rather than
in the generated sources or the spec. A spec-side `discriminator` was
ruled out first: v6.6.0 emits the identical collapsed model with and
without one (the existing afm discriminators generate an empty
`discriminator_value_class_map`). Generator v7's `python` generator does
emit a proper `Union`, so this is interim until that migration.
`set_attribute` now validates against the union of the members' types and
enums. This loses no checking - the value is still validated against the
composed schemas by `validate_get_composed_info`; only the parent's bogus
narrowed constraints are widened. `attempt_convert_item` also had to stop
re-raising on the first candidate class when `must_convert` is set, since
a union property has several candidates and the first is not necessarily
the match.
The defect was repo-wide: an audit found 25 collapsed enums and 47
collapsed types across 161 composed models. Fixing it generically retires
the per-site workarounds it has been accumulating, starting with the
`NotificationChannelDestination.allowed_values` monkeypatch removed in the
following commit. Only `model_utils.py` changes in the generated tree.
`CatalogSmtp` and `CatalogDefaultSmtp` had been sitting commented out with a
TODO blaming the generated client:
# TODO: there is an issue with generated client which causes these two
# classes to fail. type in declarative_notification_channel_destination.py
# contains only WEBHOOK as valid value
That was the oneOf-flattening defect fixed in the previous commit, so
`destination` could only ever be a webhook. With the generated composed model
now accepting every member, add the missing destinations and widen the union:
* CatalogSmtp - custom SMTP server
* CatalogDefaultSmtp - the platform's own mail server
* CatalogInPlatform - in-platform notifications
`destination` becomes `CatalogNotificationChannelDestination`, the union the
commented-out code intended.
Also drop the runtime monkeypatch that re-populated
`NotificationChannelDestination.allowed_values[("type",)]`. It treated one
symptom of the same defect from outside the generated client; the template fix
covers every collapsed composed model, so patching class attributes at import
time is no longer needed.
Reading a channel needs an explicit `from_api` rather than cattrs: the four
destination classes have no uniquely-required field to disambiguate a union on
(IN_PLATFORM carries nothing but its type), so dispatch on `type` the way
`_provider_config_from_api` does for LLM providers. It keeps only the fields
each class declares, because the API sends some we do not model - reading a
webhook returns `has_secret_key` - and dropping those matches what cattrs did
before and keeps reads working when the API grows a field.

Traverse nested composed members when merging metadata.
The helpers inspect only direct members. If a direct member is another composed model, its openapi_types and allowed_values are already flattened. Variants inside that nested composition remain absent. A valid nested variant then fails type or enum validation.
Recursively merge composed children, with cycle protection, and add a nested-composition regression case.

providerConfigon an LLM provider only accepted a singletype, makingcreate_llm_provider()/update_llm_provider()unusable for every other provider. Reported against 1.73.0, where the accepted value wasANTHROPIC; on master it wasOPENAI.

Not stale generation - regenerating from the committed specs produced a byte-identical tree. The
python-priorgenerator flattens aoneOf's members into the composed parent model, but for a property that several members declare it keeps only the last member's value. Two things collapse:allowed_values[('type',)]holds one member's enum, so the parent accepts exactly one variant - and which one depends on the order of theoneOfarray in the OpenAPI document. That is why 1.73.0 accepted onlyANTHROPICwhile master accepted onlyOPENAI: the backend reordered the array, nothing else changed.openapi_types[prop]holds one member's class, so the nestedauthunion could not carry Bedrock or Azure Foundry auth either.

Fixed in the custom templates so it survives regeneration, rather than in the generated sources or the spec.
Ruled out first:
discriminator- v6.6.0 emits the identical collapsed model with and without one (verified on a minimal 2-variant spec). The existing afm discriminators corroborate it:key_config.pygenerates an emptydiscriminator_value_class_map.pythongenerator does emit a properUnionwithactual_instance, so this is interim until that migration.set_attributenow validates against the union of the members' types and enums. No validation is lost - the value is still checked against the composed schemas byvalidate_get_composed_info; only the parent's bogus narrowed constraints are widened.attempt_convert_itemalso had to stop re-raising on the first candidate class whenmust_convertis set, since a union property has several candidates and the first is not necessarily the match.Only

1.
fix: accept every oneOf variant in generated composed models- the template fix plus regeneration, and LLM provider regression tests.2.
feat: support SMTP, default SMTP and in-platform notification channels- the same defect had already cost the SDK a feature:With the generic fix in place, adds
CatalogSmtp,CatalogDefaultSmtpandCatalogInPlatform, and widensdestinationtoCatalogNotificationChannelDestination- the union the commented-out code intended. Also drops the runtimeNotificationChannelDestination.allowed_valuesmonkeypatch added since: it treated one symptom of the same defect from outside the generated client. The class attribute is still collapsed ({'IN_PLATFORM': 'IN_PLATFORM'}) and all four destinations now construct anyway, which a test pins.Reading a channel needs an explicit
from_apirather than cattrs: the four destination classes have no uniquely-required field to disambiguate a union on (IN_PLATFORMcarries nothing but its type), so it dispatches ontypethe way_provider_config_from_apidoes for LLM providers.Verification
Original repro, all three SDK-supported provider types:
Both test files are non-vacuous: reverting only the generated
model_utils.pyturns 9 behavioural notification-channel cases red and breaks collection of the LLM tests on the helper imports.gooddata-sdk

from_api: reading a webhook returnshas_secret_key, whichCatalogWebhookdoes not model, and the explicit constructor raisedTypeErrorwhere cattrs had silently ignored it.from_apinow keeps only the fields each class declares, preserving that tolerance.layout_notification_channels.yaml, so the recorded test still covers webhook only.ANTHROPICprovider variant with no correspondingCatalogAnthropicProviderConfigin the SDK.
