Steps to reproduce

When I use the agent's react mode, if a single conversation round exceeds 250 seconds, an error occurs with the following message:
Failed to transform agent message: PluginInvokeError: {"args":{},"error_type":"Exception","message":"invocation exited without response"}

I have configured the environment variables and Nginx as follows:
.env:
WORKFLOW_MAX_EXECUTION_TIME=1800
GUNICORN_TIMEOUT=1800
nginx:
proxy_read_timeout 1800s;
proxy_send_timeout 1800s;

✔️ Expected Behavior

It should be possible to freely configure the duration of a single conversation round in the agent node’s react mode to prevent timeouts, as many operations cannot be performed at the moment.

❌ Actual Behavior

agent node return PluginInvokeError: {"args":{},"error_type":"Exception","message":"invocation exited without response"}
