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

[Sumbal Rizwan (107481)]

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
