tl:dr I have a problem with the creation of a refresh token for one guy.
Im running a service where I implement esi pulls on google sheets for peoples.
For this I have to create dev. application and refresh tokens with my customers.
I have a Google Sheet with some scripts for this task.
So I have only one customer where it always returns “malformed” refresh tokens.
But for everyone else it works fine.
The refresh tooken looks like eg.: DGDFNSDEzk2BPCFaf7dcRg==
normaly it should look like: 2dkPUyX7fEDRTPSVifZIhqNqRTHl-2epIVfDfE4bxd3f2tzfV_zYM8WVra_JKnuK0
ESI pulls with the upper ref. token are returning “malformed” refresh token errors.
The customer is chinese and he is also my first chinese customer.
I dont know how to fix this problem. It feels like its something server sided or because his google/ os/ eve account is chinese idk?
Does someone know how to fix this?
