Unfortunately I m unable to share the exact code as is but I think this is the gist of it ```item ids filepaths = zip get output filepaths context item ids temp data items = import file map item ids filepaths load futures = load items into lookup map temp data items unmapped lookup name ```

In the Prefect Cloud application I see a few of the `import file` tasks crashed but the `Run Count` is 0

Adam Eury · Answer

All Prefect Cloud shows for the crashed `import file` tasks is ```Crash detected Execution was interrupted by an unexpected exception ```

Thank you We will try enabling debug logs and yes that makes sense
