PDF Generation word Template corrupt issue

Hi Team,

We are experiencing issues while generating pdf .

Below is the same response we are getting:

{'error': {'code': 'CORRUPT_DOCUMENT', 'message': 'The input file appears to be corrupted and cannot be processed.; requestId=Cecch6YGWuBdKMOfpfsg5WrceBecckGz', 'status': 400}, 'status': 'failed'}

We have some word templates at our side which we use to generate pdf. But when we are editing them and then using , we are getting this error.  Even opening them and saving without any changes also making it faill, I also didnt find any place to raise ticket. Kindly update us what is the issue and how can we resolve it. 

Thanks
