Phenomenon:
The App SDK returns an error such as "Illegal Client" or "Signature Error" (error codes ILLEGAL_CLIENT_ID, SING_VALIDATE_FALED).
Cause of the Issue:
There is an inconsistency between the package name, AppKey, AppSecret, SHA256, and the configuration on the Tuya IoT platform.
Troubleshooting Steps:
1.Check the package name: Verify the configured package name on the Tuya IoT platform under App-App SDK-Optional Configuration, and compare it with the local project to ensure they match.
2.Check AppKey and AppSecret: On the Tuya IoT platform, locate the AppKey and AppSecret under App-App SDK-Your Application-Obtain Key, and ensure the local project is configured with the correct AppKey and AppSecret. Refer to the development documentation for configuration instructions:
iOS Development Docmentation
Android Development Docmentation.
3.For Android developments, check SHA256: Verify that the SHA256 has been uploaded on the Tuya IoT platform under App-App SDK-Your Application-Obtain Key-Android Signature Certificate-Add SHA256. Instructions for generating SHA256 can be found in the Documentation.
