[BUG] - 'browser' object has no attribute 'signature'

[kbyatnal]

Describe the bug

I think this may be a similar issue as the 'verifyFp' problem. It happens occasionally, despite my proxy server being in the US.

Are you using a free proxy? I'd imagine TikTok has denied requests from known free proxies.

Could you run this again and give the result while enabling debug mode? api = TikTokApi(debug=True)

[kbyatnal]

Nope, using a paid proxy.

I'm wondering if it could be related to the latest package update. Before, I would run into this issue 10% of the time and a simple retry would fix.

I updated the package this morning and now, I'm running into this issue 100% of the time - I can't get a single call to succeed (with no changes in the IPs being used).

[davidteather]

I'll be releasing an update that hopefully fixes this later today.

[kbyatnal]

Thanks! Just in case this is helpful - this is even happening when I try calling the API locally (without a proxy) from my residential IP. I can access TikTok just fine otherwise.

[davidteather]

Alright I released a new version does this one seem to help? It's strange it doesn't work on your residential ip.

[kbyatnal]

Might be an issue with formatting one of the parameters

[davidteather]

Are you able to open this link without errors? That's the only real change I've made to 2 versions ago.

[kbyatnal]

Yup, no issue with opening that link. Will keep digging...

[hoylemd]

I'm running into this now - it happens consistently every time I try to retrieve something:

from TikTokApi import TikTokApi
api = TikTokApi()

results = 10

trending = api.trending(count=results)

produces:

Class initialized
[W:pyppeteer.chromium_downloader] start chromium download.
Download may take a few minutes.
The following error occurred, but it was ignored.
'browser' object has no attribute 'timezone_name'
[W:pyppeteer.chromium_downloader] start chromium download.

AttributeError: 'browser' object has no attribute 'verifyFp'

I tried adding a default fields to the browser class for verifyFp and signature, but then I just get empty responses (which fail JSON parsing, raising simplejson.errors.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[hoylemd]

Following https://github.com/davidteather/TikTok-Api/issues/178#issuecomment-657244793 fixed it.

@davidteather Might be worth adding that to the installation instructions. Seems to be required now

[davidteather]

Ok I'll close this issue then. @hoylemd it's not usually required. It automatically installs on the test servers for me

[hoylemd]

Maybe it's just a mac thing? Either way, there seem to a lot of issues posted where that's the solution. Might save you and other some time to stick it in the readme. Just a suggestion :)
