Experiencing error "Hold it right there" while trying to download PDF of Submissions

When trying to download a pdf of a submission on any of our forms, we are intermittently experience an error where instead of the pdf of the form submission we are seeing a pdf stating "Hold it right there", screenshots below:

This does not happen every time however, sometimes the submission loads find, sometimes it gives the above - I have tried clicking the download pdf again and ones that worked fine intitially then give this error and some that initially gave the error subsequently worked as normal.

This is occuring on multiple different forms.

We are sorry for this inconvenience.

This problem has already been reported and fixed. Could you please try to download again and do let us know if the issue still persists on your side. 

Thank you in advance for your understanding.
