PR Preview relies on a number of web services to run. There seems to be an issue with the following one:

🚨 Spec Generator - Spec Generator is the web service used to build bikeshed/ReSpec specs

This seems to be an issue with the Spec Generator service. PR Preview doesn't manage this service and so has no control over it. If you've identified an issue with it, you can report the issue to the maintainers of Spec Generator directly. Please be courteous. Thank you!

If you don't have enough information above to solve the error by yourself or if the issue doesn't seem related to Spec Generator, you can file an issue with PR Preview.
