Error in accessing the credentials of semantic model

Hey everyone,

I'm trying to access a Power BI semantic model using the API, but I keep running into an "Invalid Token" error. I've followed the authentication process, but something seems to be off.

Here’s what I’ve done so far:

• Used Azure AD to authenticate and get a token
• Passed the token in the API request headers
• Ensured that I have the right permissions in Power BI
• Tried different scopes and grant types

Despite this, I still keep getting the "Invalid Token" error. Has anyone faced this issue before? Any advice on what might be going wrong or how to troubleshoot this?

Thanks in advance for any help!
