Error occurred during project sending to controller agent

Hello,
i set up neoload web using docker. I can log in and have also connected a controller and the LG. After uploading a test as a ZIP and running it, I get the following error message.

Could it be that I configured the all-in-one compose incorrectly?

Or is it because I did not use the yaml file to create the controller and LG.

Thanks for the support
