error: EOF while parsing an object

[mattyn]

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 15.7.4 (24G517)

Expected behaviour

I don't expect Kiro to encounter unrecoverable errors when writing source files.

Actual behaviour

Kiro repeatedly runs in to this error when trying to write a particular source file:

Kiro is having trouble responding right now: 
   0: Failed to receive the next message: request_id: 79743423-0033-4872-bff4-a24131b0280d, error: EOF while parsing an object at line 1 column 84

Location:
   crates/chat-cli/src/cli/chat/mod.rs:1524

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.

It doesn't seem to be consistent for every source file, but for the particular workflow I'm trying to run it hits it every time.

Steps to reproduce

I don't know how to reproduce this in general, but it is reliably reproduced in my project.
