Authentication issue while reversing/refunding an order

Hello,

While trying to reversing or refunding an order, I manage to click the button in my Sales performance dashboard and trigger authentication. After choosing my account, it loads indefinitely on "Authenticating", and given the following javascript error :

Error handling response: TypeError: Cannot read property 'match' of undefined
at chrome-extension://pekljbkpgnpphbkgjbfgiiclemodfpen/js/galaxy.js:97:445

Have you seen or having the same issue and how to go through ?

Thank you for your help !
