That error means your Azure Function’s language worker (the process that runs your code) wasn’t ready yet when the function tried to run.
It usually happens because of a cold start, scale event, or brief platform maintenance.
Since it fixed itself right after, it’s just a temporary initialization glitch, not a real bug.
If it happens often — enable Always On or check if your app is scaling too frequently.
