Power Automate Flow Fail

I have a flow from forms-teams- planner and recently I have gotten this error message. This is the first time for it. Does anyone know what this means? I am assuming that I can't have more than 225 characters in the title, but it goes into a planner.

Schema validation has failed. Validation for field 'Title', on entity 'Task' has failed: The field cannot be longer than 255 characters.
