Error "Item ‘rs_ABCD’ of type ‘reasoning’ was provided without its required..." when using CodeInterpreter

[molefrog]

Describe the bug

We have started to experience error of type "Item ‘rs_ABCD’ of type ‘reasoning’ was provided without its required following item" when an agent does a handoff to another agent (o4-mini with low effort to o4-mini with medium effort).

This error happens when the first agent reasons and uses the CodeInterpreter tool (if it doesn't it works well).

This might be related to this issue from the Developer Community.

Debug information

• Agents SDK version: (e.g. v0.1.0)
• Python version (e.g. Python 3.11)

Thank you for taking the time to report this and we're sorry about the disruption. At a glance, this looks like an issue on the API server side. If there is anything to change on this SDK side, we as the maintainer of this SDK will quickly work on it too.

Thank you for your reply. This does indeed look like a regression in the API, since we were using the same (latest) version of the SDK before the error appeared.

I did a simple test yesterday and I can confirm that the issue still persists. I don't know if this can be helpful, but this discussion might be related:
