Token expiring in Power BI embedded (error 403)

[gcanelon]

Hello community. We are trying to embed a Power BI report using the ReactJS framework and npm installator with the following configuration:

<Report
      

      

        tokenType="Aad"
      

      

        accessToken="H4s...sc2V9fQ=="
      

      

        embedUrl="https://app.powerbi.com/reportEmbed?reportId=6300f419-XXXX-XXXX-a55e-723f417a3f2b"
      

      

        embedId="6300f419-XXXX-XXXX-a55e-723f417a3f2b"
      

      

        reportMode="View"
      

      

        datasetId={datasetId}
      

      

        groupId={groupId}
      

      

        extraSettings={extraSettings}
      

      

        permissions="View"
      

      

        style={reportStyle}
      

      

        />
      

     
      

   Where datasetId and group Id are delared in the extraSettings as follows:

 const extraSettings = {
        

        

          filterPaneEnabled: false,
        

        

          navContentPaneEnabled: false,
        

        

          hideErrors: false
        

        

         };
        

 The problem is that, althout it initially works fine, after a while I get a error 403 when loading the report. I obtained the accessToken via postman and also using this post  

https://api.powerbi.com/v1.0/myorg/GenerateToken in the documentation located at

https://docs.microsoft.com/en-us/rest/api/power-bi/embedtoken/generatetoken#code-try-0

Is it possible to create some sort of API inside mi project to automatically generate an accessToken, with the Power BI Bearer Token as it expires?

Thanks in advance for your help.

HI @gcanelon,

You can consider storage the resulting token string and expired date(expiration field) to variables or session and modify yours generate token function to add if statement to compare current date time and cache variables.
After these steps, your invoke token function will force check the expiry date from caches and regenerate the token if they expired.
