Receiving the error "Object reference not set to an instance of an object."

  • Project Client error message that "Object reference not set to an instance of an object" when ingesting multiple PDFs as compound objects
Applies to
  • Project Client

The most common cause of this error is when attempting to ingest multiple PDFs via Object List from a tab-delimited file while Convert PDF to compound object is turned on in the Project Settings Manager. Attempting to ingest smaller batches of PDF files or ingesting them one at a time is the only way to work around this limitation in the Project Client.

Additional troubleshooting steps if the above does not prevent this error:

  1. Reboot the computer to attempt to clear memory.
  2. Attempt to ingest again, and if the same error is received contact OCLC Support for additional assistance
