Hello Katalon Community,

I’m encountering an issue while working with a SOAP API in Katalon Studio. I’m receiving the error message “ParseError at [row,col]:[1,1] Message Content is not allowed in prolog” and need some help to resolve it.

Here are the details of my problem:

  1. I’m using Katalon Studio to send a SOAP request to a specific API.
  2. The request seems to be well-formed, and I’ve double-checked the request body and headers.
  3. However, the API is responding with the mentioned error, and I can’t proceed.

I’m not sure what is causing this error, and I would appreciate any guidance or suggestions on how to troubleshoot and resolve this issue.

Thank you in advance for your assistance!

Hi,

Can you share the response body? The error says something wrong with the response object

Hi @nsyahirahzmi,

Does your SOAP message contain binary files?
