[Error] :1:62: Document is invalid: no grammar found.
The prod environment contains the following errors in startuplogs. It doesnt have a time frame to trace hence it is very difficult to identify the root cause. Did a grep of the error content in my local instance but no luck
[Error] :1:65: Document root element "getUploadTaskStatusReturn", must match DOCTYPE root "null". [Error] :1:62: Document is invalid: no grammar found.
