Code
T5103 wait-too-long
A wait of a flow is longer than its flow allows. The error names the wait.
Details
step.wait and the timeout of step.waitFor may be one year where the flow states nothing. The wait refuses its promise with this code, and nothing is saved of it.
The fix
Wait for less. Where a run truly waits longer, raise the limit: limits: { wait: '3 years' } on the flow.
