“Content body cannot be converted to new editor format" error when updating page content

Question

If we send request from Postman it works but not from code.  We are getting following response from some of the pages com.atlassian.confluence.api.service.exceptions.BadRequestException: Content body cannot be converted to new editor format. Some pages are updating and some of the pages are giving following error.

Hi @Sumbal Rizwan (107481) ,

This seems to be the same issue discussed in:

* "Content body cannot be converted to new editor format" error when updating page content

In short, that error might be returned if no user-agent is provided. See below bug for details:

* [CONFCLOUD-69720] Using REST API to update a page fails with a misleading error message if no user-agent is provided

There is also another customer affected that seems to be having a different issue that is still under investigation in that thread. Review it for details.

Cheers,
Dario
