Hi Rahul,

Can you please explain your use case in detail?. Because the posted exception can be triggered in various scenarios.

Along with what othos suggested, I would also like to understand whether you are seeing any interesting entry in the log file or not. So please review the log and let us know .

Also, find this discussion thread which talks about similar kind of issue. 

Can you please review the XSD to see if its valid?

Hi Rahul,

You can have a look at the following article  https://pdn.pega.com/support-articles/metadata-accelerator-does-not-parse-valid-xsd-file .

Thanks,

Arun

Most likely the WSDL whose URL you provided or the one you uploaded is invalid. This could also occur if there are leading spaces at the beginning of the WSDL content.
