Since I set up push notifications for my Flutter app following this tutorial , my Flutter app no ​​longer builds for iOS in the CD pipeline. I get the following error:

My pipeline looks like this:

Everything works as expected in the simulator. However, I think that the problem isn't related to the pipeline. Instead I think it is related to the "Signing Capabilities" in X-Code:

Thanks for your help!
