"Unsupported Confluence API call" when using versions >2.4.0

[massdosage]

We use Sphinx and this extension to convert a number of .md and .rst files to HTML and then upload the files to Confluence. We have used this across a wide variety of projects with success for a number of years. We recently moved to the 2.5.0/1/2 versions and consistently get the below error which goes away if we downgrade to version 2.4.0. Looking at the CHANGELOG my guess is there is some bug talking to one of the v2 APIs. Happy to provide more information or run certain follow up steps if that would help you debug the root cause.
