Power BI Api approach for dynamic report generation

Hi,

I have done these steps:

1) create a copy of the dataset from a .pbix template (PostImportWithFileInGroup from c# API)

2) update datasource settings of new dataset in order to point to the right database (UpdateDatasourcesInGroup from c# API): at the moment, the databases are in the same server so credentials are valid

3) generate a token for the report with both original and new dataset with this code:

                var pbiReport = client.Reports.GetReport(groupid, reportid);

                EmbedToken embedToken;
                // Create list of dataset
                var datasetIds = new List<Guid>();

                // Add dataset associated to the report
                datasetIds.Add(Guid.Parse(pbiReport.DatasetId));

                // Append additional dataset to the list to achieve dynamic binding later
                datasetIds.Add(Guid.Parse(newreportid));

                // Get Embed token multiple resources
                var tokenRequest = new GenerateTokenRequestV2(
                    reports: new List<GenerateTokenRequestV2Report>() { new GenerateTokenRequestV2Report(reportid) },
                    datasets: datasetIds.Select(datasetId => new GenerateTokenRequestV2Dataset(datasetId.ToString())).ToList(),
                    targetWorkspaces: groupid != Guid.Empty ? new List<GenerateTokenRequestV2TargetWorkspace>() { 
                        new GenerateTokenRequestV2TargetWorkspace(groupid)
                    } : null
                );
                // Generate Embed token
                embedToken = client.EmbedToken.GenerateToken(tokenRequest);

4) create report view from JS with the correct report id

        const config = {
            type: 'report',
            tokenType: models.TokenType.Embed,
            accessToken: accessToken,
            embedUrl: embedUrl,
            id: embedReportId,
            datasetBinding: {
                datasetId: "newdatasetid", // The dataset id that you want the report to use 
            },
            datasetId: "newdatasetid",
            permissions: models.Permissions.All,
            settings: {
                // Enable this setting to remove gray shoulders from embedded report
                // background: models.BackgroundType.Transparent,
                panes: {
                    filters: {
                        expanded: false,
                        visible: true
                    },
                    pageNavigation: {
                        visible: true
                    }
                }
            }
        };

        // Embed the dashboard and display it within the div container.
        const report = powerbi.embed(embedContainer, config);

The report is blank. Also, filter visuals are empty

From console, I have seen that a call has 403 result

UPDATE:

i have refreshed credentials from the gateway with UpdateDatasource and not it seems to work fine. I will try later with multiple binding but probably the circle has been closed
