SYMTOM:
When URL API link exceeds 1053 characters, the link will get truncated after the dashboard is exported into PDF using Strategy Web 8.x.
STEPS TO REPRODUCE:
Follow the steps below to reproduce this issue:

CAUSE
Adobe imposes a limit of 1053 characters on the URL length. Therefore, the URL was not truncated during the PDF generation inside Strategy. It was truncated by the Acrobat Reader when it renders the PDF. This issue is reproduced with different versions of Adobe. Since it is not truncated by Strategy, nothing can be done on the Strategy end.
