@Marvin What can be a possible cause of a flow failing with
Process 992016 exited with status code: 1
, it crashes when triggered by the corn job, but it runs fine why run manually (in CLI),

To help you resolve the issue where your flow fails with "Process 992016 exited with status code: 1" when triggered by a cron job but runs fine manually, let's look into some possible causes: 1. Environment Differences: The environment in which the cron job runs might differ from your manual CLI environment. This can include differences in environment variables, paths, or available resources. It's worth checking the environment variables and paths in both environments to ensure consistency. 2. Permissions: Cron jobs often run with different user permissions than manual processes. Ensure that the cron user has the necessary permissions to execute the Prefect flow, access files, directories, or network resources that the flow might need. 3. Python or Prefect Path Issues: The cron environment might not have the correct Python or Prefect paths configured. Verify that the cron job has access to the same Python environment and Prefect installation as your manual execution. 4. Resource Limits: Cron jobs might have different resource limits, such as memory or CPU usage. Check if there are any such constraints imposed on cron jobs that could cause the flow to fail. 5. Error Logs: Check the logs generated by the cron job for any error messages that might give more insight into the failure. These logs might contain stack traces or error descriptions not visible in the status code. Let's also look up some Prefect documentation or GitHub issues that could relate to this problem for more insights. I am on it! It seems like there was an issue when trying to search the Prefect documentation and GitHub issues for specific details about this error. While I'm unable to fetch additional information directly from these sources right now, let's summarize some general advice: Given the nature of your issue, it's often environment-specific problems, as mentioned earlier. Make sure to double-check environment variables, permissions, and paths involved in both the cron and manual CLI execution environments. Additionally, consult any logs associated with the cron job for more specific error messages which might help pinpoint the exact issue. If problems persist, consider reaching out to the Prefect community or examining your specific implementation and configurations for further clues. Sometimes, diagnosing these differences requires diligent debugging and sometimes an extra cup of coffee—or maybe two. Remember, even Marvin had his off days! Feel free to ask if there's anything specific you'd like more help with.

@Marvin Please note that all other flows scheduled in same project runs perfectly.

Since other flows in the same project run without issues, this suggests that the problem may be specific to this particular flow's configuration or execution context. Let's dig into some more specific points that might help shed light on this: 1. Flow Logic Anomalies: Review any unique logic or external dependencies in this flow. It might be attempting to access files, network resources, or perform tasks not present in other flows. 2. Dependencies and Imports: Check if this flow requires additional Python packages or libraries that aren't accounted for, or are absent in the environment where the cron job executes. 3. Scheduling and Timing: If this flow interacts with time-sensitive data or services, it might be encountering issues at the specific cron schedules. Compare execution times when run manually versus scheduled. 4. Error Handling: Ensure the flow has proper error handling or logging to capture exceptions and provide insights, particularly when it runs in production. This might reveal hidden exceptions when run via the cron job. 5. Resource Constraints: Given the cron environment might have limited resources, ensure this flow doesn't consume more than what other flows might comfortably use. With these considerations in mind, you may want to reevaluate the components and dependencies specific to this flow in relation to its environment. Ensure it mimics closely what works in the CLI.
