[Bug] Media generation workflow nodes download remote files without a timeout

[zhonggang666]

Problem Description

Several workflow media-generation nodes download generated remote media with requests.get(...).content but do not set a timeout.

Code Locations

• apps/application/flow/step_node/image_generate_step_node/impl/base_image_generate_node.py:62
• apps/application/flow/step_node/image_to_video_step_node/impl/base_image_to_video_node.py:68
• apps/application/flow/step_node/text_to_video_step_node/impl/base_text_to_video_node.py:62

Steps to Reproduce

1. Configure an image/video generation model provider that returns an HTTP URL as the generated media result.
2. Make that URL slow, unreachable, or keep the TCP connection open without sending a complete response.
3. Run the corresponding workflow node.

Actual Result

The workflow node calls requests.get(url).content without a timeout, so the workflow execution can block for a long time or indefinitely while downloading the generated media.

Expected Result

The download should use an explicit timeout and report a controlled node error when the media cannot be fetched in time.

Impact

A bad or slow generated media URL can tie up workflow execution resources and make the node appear stuck instead of failing predictably.
