Measures the number of invocations that failed due to errors in the function (response code
4XX). This replaces the deprecated ErrorCount metric. Failed invocations may trigger a retry
attempt that succeeds. This includes:
Handled exceptions (for example, context.fail(error))
Unhandled exceptions causing the code to exit
Out of memory exceptions
Timeouts
Permissions errors
This does not include invocations that fail due to invocation rates exceeding default
concurrent limits (error code 429) or failures due to internal service errors (error code
500).
