Confluent Connect HTTP Sink Connector fails task despite config set to ignore

Question

I have an application that wants to send processed events to a third party application via their API. I set up an HTTP Sink connector from Confluent following their guide. Errors originating from kafka/confluent like wrongly structured events etc. are handled correctly and logged to a DLQ. However, when the connector sends data to the third party application and receives an error response code, the connector retries the REST x amount of times before failing the connector task, thus "killing" the connector and stopping data flow. I have tried to configure my connector according to the docs setting behavior.on.error to ignore / log:

behavior.on.error Error handling behavior setting for handling response from HTTP requests. Must be configured to one of the following:

fail Stops the connector when an error occurs.

ignore Continues to process next set of records. when error occurs.

log Logs the error message to application logs when error occurs and continues to process next set of records.

Type: string Default: fail Valid Values: one of [fail, log, ignore] Importance: low

Checking the configs of the connector after starting it also shows the configs listed properly. Is there any settings that I am setting here that are overriding eachother? Btw, in my connect worker task I am setting the variable

CONNECT_CONNECTOR_CLIENT_CONFIG_OVERRIDE_POLICY :
    value: "All"

My connector configs are:
