Oracle reports 12c creating large reports with graphs gives error (REP-271468673).

We need to create a pdf of about 1500 pages with a graph on each page.

If I remove the graph the pdf is created without any errors.

Once I insert the graph the report crashes and give the below message:

The report terminated with error:
REP-271468673: Unable to retrieve a string from the Report Builder message file. REP-271468673: .
