claude-agent-sdk execution error: JSON Parse error at withSlowLogging

[EurFelux]

Describe the bug
I encountered a log error within the SDK, but I have no idea what’s going on.

SDK execution error: 7270 |   return typeof value;
7271 | }
7272 | function withSlowLogging(operation, fn) {
7273 |   const startTime = performance.now();
7274 |   try {
7275 |     return fn();
                  ^
SyntaxError: JSON Parse error: Unexpected identifier "Usage"

Error: Process completed with exit code 1.

Run: https://github.com/CherryHQ/cherry-studio/actions/runs/20840638256/job/59874222002

To Reproduce
Sorry, I’m completely baffled by this. The Claude action settings in this workflow don’t seem to differ significantly from our other workflow settings, yet it keeps failing while the other workflows are working fine.

Expected behavior
Just don't throw an error.

Workflow yml file
https://github.com/CherryHQ/cherry-studio/blob/61aae7376af8a61ccbff5bf2b232657d4d8903b4/.github/workflows/github-issue-tracker.yml#L81

API Provider

BigModel with Anthropic API (GLM 4.7)

Additional context
I made some minor changes to the prompt and args yesterday, and since then every workflow has failed. You can see the diff here: CherryHQ/cherry-studio@43a48a4

I think this is because your prompt contained the string "--help" which is somehow getting interpreted by Claude Code as an actual CLI arg. That's causing the output of claude --help to get parsed, I believe, and it happens to start with "Usage". This is definitely a bug, thanks for flagging.
