Linux: SQX 137rc2: Error running project 'GBPJPY StrategyLab'

Workflow stopped abruptly with the above error, after generating some strategies. I tried to view one of the Strategies created by the Workflow, while the Workflow is still running. That may have triggered this error.

Expected behavior: Don't throw the error. Or at the very least, throw a warning instead of error and continue processing the Workflow.

From log file:
