Power BI Embedded Concurrent Loading Limits Causing Empty Reports in CloudConvert Screenshots

I'm building a system to generate screenshots of multiple Power BI reports, embedded at my website with different filter combinations by CloudConvert, but as I checked on Internet I think hitting concurrent loading/embed limits causing empty data in mostly generated images. Here's my flow for this:

Current Implementation

• Data Collection

  • A Script generates urls of combinations of: ReportID × Page/Tab × FilterValues
  • Total combinations: ~50,000 (but testing with smaller no. of combinations)

• CloudConvert Processing

  // Sample PHP code for calling API to create capture tasks
  $tasksArr = array();
  foreach($combinationsOfURLArr AS $embedurl){
    $taskArr[] = array(
      'capture-' . $uniqueId => [
      'operation' => 'capture-website',
      'url' => $embedurl,
      'delay' => 20, // Wait 20 seconds before capture
      'wait_until' => 'network_idle'
    );
  )
  $response = $client->post('https://api.cloudconvert.com/v2/jobs', $taskArr);
  

• Callback Handling

  • CloudConvert calls our webhook when done
  • Server downloads ZIP with screenshots

• Problem is

  First 40-50 reports: Perfect screenshots with all data

  Remaining reports: Visuals appear empty (background loads but no data)

• Successful workaround

  Processing 40 reports with 10-minute gaps works perfectly

• Diagnostics Performed

  Checked Power BI capacity limits:

  GET https://api.powerbi.com/v1.0/myorg/admin/capacities1

  Response shows mixed SKUs:

  {
    "value": [
        {"sku": "A1", ................. },
        {"sku": "P1", ................. },
        {"sku": "PP3", ................. },
        {"sku": "F64", ................. }
    ]
  }
  

• What I Need Help With

  Timing Configuration: How can I calculate optimal Delay between captures (delay parameter in CloudConverter) and

  Max. number of Tasks in a Job for CloudConverter

  Required wait time between batches

Note: I do not have access of PowerBi account, I am accessing through Service Principal credentials.

Please help me or if there any alternative of this please let me know. Thanks,
