When asked to describe an attachment image i get error: failed to pipe response

[sunny0183]

This is after project upgraded to Next 15 and React 19rc

In a chat when a document (image or pdf) is uploaded and asked to describe it, it responses with good description and looks like it finished streaming responding but then at the end of the response it throws the error.

the error happens at the api/chat/route.ts at the return result.toDataStreamResponse({});

the error is
