Problem Description

The qwen series model on Aliyun platform requires "enable_thinking": True to enable thinking mode. This parameter is not in the advanced parameter list, nor is it possible to add it as a custom parameter because that only supports strings, and the result is this error:

Desired Solution you'd like

Allow boolean type custom parameter

Alternatives Considered

Alternatively add enable_thinking parameter into the advanced parameter list, but by default this parameter should not be added to queries as other models might not support this.

Additional Context

No response

Could you share a screenshot of your custom params section?

Should have tested one more thing: I was using True and it needs true. This is working now:

Still, would be great to have this parameter added into the default list.
