Problem in connection. 'skill id invalid' Error.

[wpritom]

I'm trying to connect Tuya Cloud by the following line:

openapi.connect(USERNAME, PASSWORD, country_code, schema)

This gives me the following response:

{'code': 2406,
 'msg': 'skill id invalid',
 'success': False,
 't': 1678601679934,
 'tid': '2c049292c09d11edbcdaea52450d735d'}

I guess skill id invalid is country_code related problem. Here it is 49 since my data center is Central Europe Data Center, and location of this data center is in Germany. I found this from this doc:

I tried it with other country code under Central Europe Data Center.

Still no luck!
