Gracefully handle 'ExportManagerImpl Export is failed'

Overview:

This is an example of another error that halts data export.

2021-09-13T20:15:30,595 ERROR [vert.x-eventloop-thread-1] ExportManagerImpl Export is failed, cause: A string value cannot contain data after its closing quote (this is most likely caused by a missing comma between members); at Input Source: "MarcInput", Line: 1, Column: 2639, Member Name: ind1

We've bumped into several errors like this that completely halt the export:

Escape control characters in quoted literals  https://issues.folio.org/browse/MDEXP-426

Gracefully handle MARC records that exceed the size limit  https://issues.folio.org/browse/MDEXP-422

Can this issue be fixed so that whenever this ("ExportManagerImpl Export is failed") occurs, the error is logged and the export continues on?  This is a difficult problem because from the logs it is not possible to determine which record caused the problem.  I hadn't seen this particular error in the past so we have no idea what other errors might pop-up during the export.  My request is to deal with any error gracefully during this process.

Steps to Reproduce:

I'm not sure how to reproduce this error because we don't know what record is causing it.

Expected Results:

• The error is handled gracefully
• The status of the export is Completed with errors. 
• Not affected records are successfully exported.
• The information about the affected record is  added to the user error log using the standard entry :

  <dateandtime> ERROR A quoted literal may not contain any control character. Field name <affected fields>
  {
  "Instance UUID": "<affected record uuid>"
  "Instance HRID": "<affected record hrid>"
  "Instance Title": "<title>"
  "Inventory record link": <link to the record>
  }
  

Actual Results:

Export job fails.  Error log contains only Generic error information.
