We have an app to generate a google spreadsheet from the app. However, we
are getting this "No authentication header information" - this is error log
which means when the the app tries to update/create google sheets this
error log splits. we use google sheets api v3 and our program code is
SpreadsheetFeed feed = service.getFeed(new URL("
https://spreadsheets.google.com/feeds/spreadsheets/private/full"),
SpreadsheetFeed.class);SpreadsheetFeed
feed = service.getFeed(new URL("
https://spreadsheets.google.com/feeds/spreadsheets/private/full"),
SpreadsheetFeed.class);
we are facing issue here. service is object of SpreadsheetService. and here
we are getting java.lang.NullPointerException: No authentication header
informationjava.lang.NullPointerException: No authentication header
information.
Please review above and advise?
