Node.JS PowerBI App Owns Data for Customers w/ Service Principal (set "config.json" from a table in my database)

I'm attempting to refactor the "Node.JS PowerBI App Owns Data for Customers w/ Service Principal" code example (found HERE).

My objective is to import the data for the "config.json" from a table in my database and insert the "workspaceId" and "reportId" values from my database into the "getEmbedInfo()" function (inside the "embedConfigServices.js" file). Reason being, I want to use different configurations based on user attributes. I am using Auth0 to login users on the frontend, and I am sending the user metadata to the backend so that I can filter the database query by the user's company name.

I am able to console.log the config data, but I am having difficulty figuring out how to insert those results into the "getEmbedInfo()" function.

It feels like I'm making a simple syntax error somewhere, but I am stuck. Here's a sample of my code:

//----Code Snippet from "embedConfigServices.js" file ----//

    async function getEmbedInfo() {
      try {
        const url = ;
        const set_config = async function () {
          let response = await axios.get(url);
          const config = response.data;
          console.log(config);
        };
        set_config();
    
        const embedParams = await getEmbedParamsForSingleReport(
          config.workspaceId,
          config.reportId
        );
    
        return {
          accessToken: embedParams.embedToken.token,
          embedUrl: embedParams.reportsDetail,
          expiry: embedParams.embedToken.expiration,
          status: 200,
        };
      } catch (err) {
        return {
          status: err.status,
          error: err.statusText,
          }
        };
      }
    }

This is the error I am receiving on the frontend: "Cannot read property 'get' of undefined"

Any help would be much appreciated. Thanks in advance. Carlos
