[BUG] Write tool continously getting aborted

Description

I am on MacOS and I have v 1.1.40 installed through npm.
In my project, Write tool is continously getting aborted. This same issue used to happen when I started the project and then later the issue was somehow resolved without me making any changes.
However, now the write tool gets aborted continously.
I am using GitHub copilot as provider and Sonnet 4.5 as the model.

This issue might be a duplicate of existing issues. Please check:

Unable to use "github-copilot/claude-*" models #11009: Unable to use GitHub Copilot with Claude models - directly related provider integration issue
Can't use Claude Opus 4.5 on opencode using Github Copilot #6281: Write tool JSON parsing failed with GitHub Copilot and Claude Opus - same write tool abort pattern with GitHub Copilot provider
Error Writing Large Files (at least with Kimi K2.5) #10967: Write tool JSON parsing error on macOS with Kimi K2.5 - same write tool abort pattern on macOS
write tool sometimes has a "request was aborted" result #268: Write tool "request was aborted" error - historical duplicate of same abort symptom
Bug: Session corrupted when tool execution is aborted - missing tool_result causes API rejection #8312: Session corrupted when tool execution is aborted - explains cascading failures from tool aborts

The common pattern suggests this may be related to the GitHub Copilot provider's handling of Claude models or the Write tool's JSON parsing when used with certain providers on macOS.

Feel free to ignore if your specific case differs from these issues.

I'm seeing the exact same issue on Ubuntu Linux using Copilot and Claude Opus 4.5. OpenCode v1.1.39 and v1.1.40

@KerseyFabrications

Same as @KerseyFabrications . In my case, Claude Opus failed, then I changed to Claude Sonnet 4.5 and it could call the tool, but it failed on the next one.

After this, I tried with gpt-5.2-codex and it works.

Have the same issue with Claude Opus and Sonnet 4.5 via GitHub Copilot

im going to look into why this can happen

same issue here but i just have this with opus 4.5 from github copilot, anything else works for me

fix: add max retry limit for StreamIdleTimeoutError to prevent infini…

Same with GPT5.5

Had same issue for GPT family models, found a related PR which provides detailed diagnosis: #25511
