Hi Ng Josua,
Thank you for reaching out! I understand how frustrating that error can be — let’s get you back on track.
The error you’re seeing:
handle_error: request Id 4
{ “code”: -32002, “message”: “Invalid License Key.” }
means that the EMOTIV Cloud could not find a valid license associated with your account.
According to our documentation, this corresponds to the following:
-32002 Invalid License ID
The EMOTIV cloud cannot find the license of the user. When you call the authorize method, please make sure that you provide a valid license ID — or omit the license parameter entirely if you’re using a free function such as BCI Mental Commands.
If the issue continues, the license owner should contact EMOTIV Customer Support.
You can find the full reference here:

If you’re only using the BCI Mental Command feature, you don’t need to include the license parameter when calling the authorize method. Removing it should prevent this error from appearing.
Also, I’d love to invite you to join our official EMOTIV Discord community, where our team and other developers share projects, troubleshoot issues, and provide direct support:

I’m Giovani Florek, EMOTIV’s Developer Evangelist — feel free to reach out anytime if you’d like me to take a look at your code snippet or help you debug the authorization flow.
Best regards,
Giovani Florek
