[Bug]: Udemy Says: 'NoneType' object has no attribute 'json'

[MJ-DEV91]

What happened?

I tried to download a course with the below command:
python main.py -c https://www.udemy.com/course/docker-hands-on/learn/ --download-assets --download-captions -b *******************************************************
but I faced this error:

Expected Result

somehow this problem has a connection with IP address, if I use a VPN, then it works fine and starts downloading (everything is the same, except the IP!)

Branch

No response

[Puyodead1]

Are you able to use the udemy website without a vpn?

[MJ-DEV91]

Yeah, absolutely

[Puyodead1]

Yeah, absolutely

still having this problem? I'm not sure what would be causing this issue. Please check that you are using the latest version of the master branch. I would also suggest turning off your VPN, logging out of the Udemy website, logging back in and getting a new bearer token (just in case the other token is tied to your VPN)

[MJ-DEV91]

I just checked the master branch once again and I got a new token with VPN off, it's still the same.

[Puyodead1]

I just checked the master branch once again and I got a new token with VPN off, it's still the same.

Are you signed into the right account when you obtain the bearer token?

[MJ-DEV91]

I just checked the master branch once again and I got a new token with VPN off, it's still the same.

Are you signed into the right account when you obtain the bearer token?

yeah, believe me, the only difference is using the VPN.

In that case, I have no idea what the issue could be. the only thing i can think of would be something related to geo-location.

[mahdisky]

i have this problem,
i used the vpn and the no vpn

[Puyodead1]

i have this problem, i used the vpn and the no vpn

what version of the tool are you using? python main.py -v

[mahdisky]

version 1.1.4

[MJ-DEV91]

In that case, I have no idea what the issue could be. the only thing i can think of would be something related to geo-location.

I'm not sure if it has something to do with that,
this is the error that I'm getting:

could you send me a bearer token and the course url to test with? either through email puyodead@protonmail.com or discord Puyodead#0001

[Puyodead1]

This issue is most likely caused by Cloudflare captchas, currently there's nothing I can do about it, but I am trying a few things.

Please see this comment for a solution: #92 (comment)
I'm going to close this issue in favor of #92, feel free to comment there if you have any trouble setting up the new branch
