source=gemma4.go:287 msg="gemma4 tool call parsing failed" error="invalid character 'p' after object key:value pair" content="call:subagent{*****************}"

TL;DR

The issue with gemma4 failing a tool call is likely due to a parsing error, and checking the input data for invalid characters may provide a workaround.

Guidance

• Verify the input data being passed to the gemma4 tool call for any invalid characters, specifically looking for object key-value pairs with trailing characters.
• Check the documentation for the gemma4 tool call to ensure that the input data format is correct and supported.
• Consider validating the input data before passing it to the gemma4 tool call to prevent parsing errors.
• Review the gemma4 source code (e.g., gemma4.go:287) to understand the parsing logic and how it handles different input data formats.

Notes

The provided log output suggests a parsing error, but without more information about the input data or the expected format, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Validate and sanitize the input data before passing it to the gemma4 tool call to prevent parsing errors, as the root cause of the issue is likely related to the input data format.
