Error token Power BI server with Power Automate

Hi, pamila-barros 

It sounds like you use powerbi service instead of powerbi report server? Report Server is on-premises. 

The error screenshot you provide is hard to judge.

Please follow the tutorial to create powerbi automate button:

Trigger a cloud flow from any Power BI report - Power Automate | Microsoft Docs

There are known limitations:

• The user running the flow within the Power BI report needs to have permissions to run the flow. Grant these permissions through direct sharing by the user or by sharing to an Azure Active Directory group.
• The Power BI visual only functions with flows in a tenant's default environment. Any flow created with the visual is created in the users default environment.
• Additional manual inputs to the button are not supported at this time.
• The visual is not supported for PaaS embedded scenarios nor in Sovereign Cloud scenarios.
• Create flows that you will use with the Power BI button trigger directly within the Power BI report. Do not go directly to Power Automate to create these flows as the trigger will not have access to the data fields necessary for creating the flow.
• Power BI data will be sent to and processed in a geography where the flow is deployed.
