The error you’re encountering in your code (AttributeError: ‘NoneType’ object has no attribute ‘uid’) indicates that the token_info attribute of the TuyaOpenAPI object is None. This means the authentication process is failing to retrieve the user information, including the UID.

Here are some steps to troubleshoot the issue:

1. Verify API Credentials:

Double-check your EMAIL, PASSWORD, ACCESS_ID, and ACCESS_KEY in the file. Ensure they are correct for your Tuya account and the specific smart home schema you’re using (APP.value).

2. Check Network Connectivity:

Make sure your device has a stable internet connection. A failing connection can disrupt the authentication process.

3. Tuya API Status:

The Tuya API might be temporarily unavailable. Check online resources or forums to see if others are experiencing similar issues.

4. Code Review:

Ensure you’re following the tuya-iot-py-sdk documentation for authentication. Refer to the specific steps required for the Smart Home AuthType you’re using.

5. Update SDK (if necessary):

While you mentioned installing tuya-iot-py-sdk using pip3, consider checking if there are any newer versions available. You can update it using:

pip3 install --upgrade tuya-iot-py-sdk

Debugging Tips

Add print statements before the lines where the error occurs (around lines 41 and 239 in your code). Print the values of openapi.token_info and other relevant variables to see if they are populated correctly after the openapi.connect call.

If none of these solutions work, consider looking at the Tuya API documentation and the tuya-iot-py-sdk library documentation for more specific troubleshooting steps related to authentication errors. You might also find helpful information by searching online forums or communities for similar issues encountered by other users.
