Looks like your code there is Kotlin. The issue you’re hitting isn’t a CrewAI thing (on the client side), but more likely something on your Kotlin server’s end.
In that snippet, you’re setting up a JSON Schema, and timeoutMs is defined like:
put("type", "number")
Now, according to the JSON Schema docs, number accepts any numeric type, either integer or floating. So, if your server is only expecting an integer, you need to change that to:
put("type", "integer")
