I'm glad that it has resolved. Looking through our internal system I don't see any Logic App tickets that would have caused this error.
It's a good idea to setup your system to handle situations where the platform is having issues- while we are continually improving in this area, problems are going to crop up occasionally.
How are you doing you error handling that it didn't trigger? Is it inside the Logic App or separately in something like Azure Monitor? Using the error path inside Logic Apps will catch most things like malformed data, but setting up Azure Monitor will help catch things like this where it is the platform that is having problems.
