Hey @wenjiesha

Thanks for your feedback.

Could you open the DevTools → Network tab, filter for requests with the keyword wc/lsdk, then find the x-zm-trackingid property in the response headers and share it with us?

Thanks
Vic

Thank you for the quick reply!

X-Zm-Trackingid below

v=2.0;clid=aw1;rid=WEB_a1d1a48397c39583cb1452ae854b16ff

The JWT this time is

Hi @wenjiesha

I did a preliminary validation of the JWT token on jwt.io, and it shows: ‘is not encoded correctly using base64url’.

Could you please check the logic used to generate the JWT?

Thanks
Vic

Thank you @vic.yang !
The issue is that the JWT generation logic uses base64 instead of base64url encoding
This is fixed now
