I load Excel Online spreadsheet using Javascript EWA. I see a number of errors like the below in console.logs. These doesn't seem to impact my pages though. How can I suppress these messages?
Refused to get unsafe header "X-EndSession"
Refused to get unsafe header "X-CorrelationId"
Refused to get unsafe header "X-OfficeFE"
and a number of others that start with Refused to get unsafe header ..
How do I fix this?
