Truncation bug

[zakiali]

Describe the bug

During a long session where truncation is triggered, the UI session ends up having the following error Failed to buffer the request body: length limit exceeded. This is after truncation occurs successfully (as seen from the logs). This was assumed to be because the context is too long, but this seems to be a different error mode.

A clear and concise description of what the bug is.
