Getting 500 error when using MCP

Final speech.

You need to have desktop mode install and enable the Enable Dev Mode MCP Server function.

Already did. As you can see the `get_image` task is running successfully, with a green check. But afterward the 500 error pops out.
As a side note, my MCP can run get_code correctly

The same error occurs.

`get_image` works well but i see the 500 error.

The mcp worked well few hours ago but it keeps failing now.

Hey ​@Bors ​@fin.chen 

Thanks for flagging. Are you still experiencing this issue? This might be related to the Claude API on their end, but if you're continuing to encounter this error, it would be really helpful if you could submit a formal bug report with detailed reproduction steps.

You can do this here: https://help.figma.com/hc/en-us/articles/360041468234-Submit-a-bug-report. The more information you can provide about when and how this occurs, the better our team can investigate.

Thanks for your patience

Hi ​@y_toku 

I changed to gemini 2.5 pro / GTP-4.1 / o4-mini and it did not show 500 error. 
However, now the `get_code` seems to be running infinitely when using gemini 2.5 pro / GPT-4.1 / o4-mini. I’ve filed a bug report. Thanks for the help.

can confirm getting the same bug with the get image running infinitely
