New 401 error without code change on my end

[mpoletiek1]

Hello,

My javascript buttons with a sandbox client-id were working just fine until recently.

All of a sudden, when testing, clicking on a button generates a PayPal login popup that immediately disappears. Looking at the web console I see the following error:

Update_client_config_error: graphql returned status 401

Again, no known changes on my end.

Did some additional testing and this only seems to happen in Firefox.

This issue was caused by 'Privacy Badger' extension in my firefox browser.

Solved.
