I have a pipeline reading a csv file and doing POST request to an API for each lines.

POST request are done via a HTTP Client processor but I can receive a 200 response for a sucessful item created or a 400 with error fields. I want to send these errors to RabbitMQ but I don't know how to handle the 400 response, the pipeline stops and throw an error.

How to catch those 400 responses?

Edit: I followed @metadaddy 's answer to send error to another pipeline. Unfortunately I still don't retrieve the response. Here is some screenshots for easier readability.

content of the error file:

{ "Field2":"xxx", "Field2":"xxx, [...] }

You can set On Record Error on the HTTP Client Processor to Send to Error, then configure error handling for the pipeline to send error records to a second pipeline, from which you can send them to RabbitMQ.

Alternatively, you could use one of the script evaluators to send the POST request, and handle the response in the script.

Thanks for you answer. I have done the first solution it works well but I get only the payload with data sent. Not the received response. Is it possible to get it too?

Looking at the code, the response body should be in the error. Dump the entire record to disk as JSON and you should be able to see it.

I get the same record, a list of objects `{fields1: value, field2: value}` but still not the response. Did I miss some option ?

Hi, I edited my question with screenshots of the pipeline for easier readability.
