Error with code 40102 when calling the endpoint "<https://api.heygen.com/v1/video.generate"> using the trial API key.

Hello. First of all, greetings.

I have a problem: When I call the mentioned endpoint with my trial API key, I get the message: "Unauthorized" and the error code: 40102.

I have the free plan. Do I have to purchase the enterprise plan to use the trial API key? Or what could be happening?

I really appreciate your time.
