Error with Content Blocks on TYPO3 Version 13

[stattmal]

Describe the bug
Trying the TYPO3 Headless API on a new TYPO3 version 13, including the new TYPO3 CMS Content Blocks extension, results in an error when requesting the JSON response.

To Reproduce
Steps to reproduce the behavior:

1. Perform a fresh TYPO3 13.2.1 installation.
2. Add a new content block with the following command:

   typo3/sysext/core/bin/typo3 make:content-block --content-type="content-element" --vendor="my-vendor" --name="my-first-content-element" --title="My shiny new Content Element" --extension="my-extension"
   

3. Add the content block as content on a new page.
4. Try to load the JSON response.
5. See error.

Expected behavior
A JSON response with the newly added content based on the content blocks.

Additional context
We have been using your headless plugin for a while and would love to have support for TYPO3 version 13 when requesting new content blocks.

Hi @stattmal I have this on roadmap for new major version of our extension, but for I have to wait for final API in core to start adapting it for ext:headless

howto get headless running with TYPO3 13?
I set up a new composer based TYPO3 13.2.1 - downloaded the last master from headless and changed the dependencies to TYPO3 13.2. So I could install headless but the backend results in 500 Error.
@tmotyl is there a release plan for headless for TYPO3 13.2 ?

@cehret you can test now headless with v13 on branch t3v13 (based on v4.4 with added v13 support) see more at #778

I still get this with TYPO3 v13.4.0 and headless 4.5.0.

In JSON, I only have

content: "Oops, an error occurred! Request: d6adf10b3e734",

And in logfile warnings:

Exception: PHP Warning: Trying to access array offset on null in /var/www/html/app/vendor/friendsoftypo3/headless/Classes/ContentObject/JsonContentContentObject.php line 186, in file /var/www/html/app/vendor/typo3/cms-core/Classes/Error/ErrorHandler.php:141

Hi @carsten-wilhelm most probably, with release v4.5.0 we added support for v13, content block extension is not supported at the moment.

Any plans for supporting the content block extension?
