Solutions

1. Fix the condition reported by the error: Interrupted waiting for command: {} {}
2. Check the throwing call site and ensure its documented preconditions (argument values, types, environment, or configuration) are satisfied before the call.

Example fix

Validate inputs and environment so that the failing condition does not occur: Interrupted waiting for command: {} {}
