tRESTClient – Error 415 Unsupported Media Type while uploading CSV as multipart/form-data

Hi Community,

I’m working on an integration where I need to push a CSV file to an API endpoint using Talend tRESTClient.
The API expects the file to be uploaded with Content-Type: multipart/form-data.

But when I run the job, I keep getting this error:

Exception in component tRESTClient_2
jakarta.ws.rs.NotSupportedException: HTTP 415 Unsupported Media Type

I gave this Configuration inside tRestclient

Any guidance would be appreciated.

Thanks in advance!

Hello @MohamedArsath
Are you able to make API calls to the same endpoint using Postman? Any Content-Encoding setting requirement for that?

Best regards

Sabrina
