PDF Files as Data source - Error with pdf2text.dll

I'm striking exactly the same issue - first observed today.  This seems like an obvious mistake on the Power BI refresh servers - hope it can be rectified quickly.

Hello - I am experiencing the same issue.  I am able to refresh via the desktop, but scheduled refresh in the service is failing.  

Having the same issue as of Sunday Oct 11th 

Having the same issue from 12-Oct-20 (IST) , could not find any soluton on this. Dataset refreshes fine in desktop file, but this failure is from PBI service.

Same issue here. Appears to be a PBI service wide issue...

Same error here.  Started happening some time during the weekend.  I can refresh fine on desktop, but erroring out online.

Same here. Desktop works fine, but not online

The issue is clearly related to the online service with pdf sources.

I've modified my report, deleting all queries related to pdf, and now the dataset refresh OK.

I've opend a ticket to support, and I'm providing them with logs...

I  hope this get fix fast.
