Management api 400 bad request error when assign a role to user

[osamass9000]

I want to use the management API to assign a specific role to a user
but every time I get 400 error
I use flask and this is my code

and I get my MGMT_API_ACCESS_TOKEN from API explorer and it has the requested
scopes (read: roles, update: users)
and I used the postman too and get an error (I used request data as a params on postman) like
‘?roles=[rol_ZNrwNNQqwSOmhpov]’ and still not working any help

Hi @osamass9000,

It looks like you are getting a timeout, not a 400 error. It may have to do with the user ID not being encoded.

Try that and let us know if it works.
