Export Not Working

[christhepianist]

Descriptive summary

We are running Hyku version 6 with all main commits through 69b3e60.

The export function is not working correctly. I can create an export:

Click "Create and Export"

The result is a message stating that the export was created and that the download link would appear. However, below that, the system records it with a "failed" status:

In looking at the details of the import, the error is provided, as well as the error trace (which continues below the screenshot):

There is a similar result when exporting metadata and files:

There is a similar result when exporting using the BagIt parser.

Rationale

This export functionality worked in version 5. It is required for libraries that want to update their metadata using the round-trip method, which is common for those uploading multiple items at one time.

Expected behavior

When choosing the type of export, the system should provide files to be downloaded based on the parameters set.

Actual behavior

The system states that the export has run and that a download file is forthcoming, but it also states that it was a failure and provides information on the error(s).

Steps to reproduce the behavior

1. Open Exporters in Hyku
2. Choose "New"
3. Complete the form
4. "Create and Export"
