Snaplogic integration using Netsuite

All,

We are experiencing an intermittent issue with our Netsuite integration.

Error: Unable to parse XML schema information from the given WSDL

Resolution:
Please validate XSD and correct

Reason:
Premature end of file.

Caused by: org.xml.sax.SAXParseException; systemId: https://4515368-sb2.suitetalk.api.netsuite.com/xsd/activities/v2019_1_0/schedulingTypes.xsd; lineNumber: 1; columnNumber: 1;

I believe this is a issue with the Netsuite instance and the snaplogic is not been able to read the xml schema correctly. As this is issue intermittent therefore I am not sure why it is the root cause.

Thank You,
Sombit
