Python Error when running wizard

[Brunius]

Hi all,

I'm trying to do first-time setup, following the instructions here. I'm up to step 4.

I have entered the API Key, Secret, and a device ID, copy and pasted from the Tuya website, and confirmed through scan.

I encounter the following error:

$ python -m tinytuya wizard
TinyTuya Setup Wizard [1.12.11]

    Existing settings:
        API Key=*******************************
        Secret=*********************************
        DeviceID=******************************
        Region=eu

    Use existing credentials (Y/n): y

    "Cloud _gettoken() failed: %r" % response_dict['msg'],
KeyError: 'msg'

I have found the following issues which seem to have a similar problem:

Python ERROR when trying to run 'wizzard' #20 Error when using 'wizzard' #19

The resolution for these issues seemed to be to ensure that the correct permissions are enabled in the Tuya IoT platform. As far as I can tell, I have the correct permissions:

Are there further permissions I should be requesting? Have I missed a step?

Any advice you can provide would be much appreciated.

Hmm, those all blow up much later in the process, you should't be encountering errors in _gettoken(). What does this result in:

import tinytuya

c = tinytuya.Cloud(initial_token=True)
c.token = None
print(c._tuyaplatform('token?grant_type=1'))

[Brunius]

{'Error': 'Missing Tuya Cloud Key and Secret', 'Err': '909', 'Payload': "Cloud _tuyaplatform() invalid response: b'400 Bad Request'"}

Should that be pulling from the same saved credentials that wizard offers to use? Or is there an assumption that I have provided something?

[uzlonewolf]

Yes, it should automatically pull them from tinytuya.json (same as the wizard) when not provided. You can also pass them in explicitly if needed:

import tinytuya

c = tinytuya.Cloud(apiRegion="eu", apiKey="...", apiSecret="...", apiDeviceID"...", initial_token=True)
c.token = None
print(c._tuyaplatform('token?grant_type=1'))

Got a good result from this one -

{
    'result': {
        'access_token': '18d829aaec28a84d1c4d4f01cc66****',

}

Hmm, it should work then. If you open tinytuya.json in a text editor, is there any whitespace or funny characters inside the quotes?

[uzlonewolf]

@jasonacox it looks like https://github.com/jasonacox/tinytuya/blob/master/tinytuya/Cloud.py#L266 should be updated to handle the cases where _tuyaplatform() returned None or an error_json() (via response_dict). I'll see if I can do something about that tomorrow if I have time. Edit: we should probably also strip whitespace/unicode or throw an error if any are found in the loaded/passed values.

[Brunius]

Hmm, it should work then. If you open tinytuya.json in a text editor, is there any whitespace or funny characters inside the quotes?

Some unicode characters:

For example, device id: "apiDeviceID": "\u001b[F\u001b[200~32624843c44f33ef51ac\u001b[201~" Should probably be :"apiDeviceID": "32624843c44f33ef51ac"

I would guess that this is due to my cut + pasting and not having the whitespace trimmed from the end?

[Brunius]

I've just edited tinytuya.json to remove the unicode - it all seems to work just as expected.

[uzlonewolf]

Yep, that would do it. Fix that and you should be good to go. I'll add some sanity checking of the passed values tomorrow while I'm in there.

Thanks @uzlonewolf - I've been traveling quite a bit so please feel free to submit the update or I'll get to it later this weekend. 🙏
