No configuration found with the specified id

Error message

No configuration found with the specified id

What it means

Thrown by FacebookPixelController.CustomEventList when _facebookPixelService.GetConfigurationByIdAsync(searchModel.ConfigurationId) returns null. The action expects an existing Facebook Pixel configuration row; a missing row means the grid request references a configuration that does not exist.

Solutions

  1. Reload the parent configuration list to get a valid ConfigurationId.
  2. Guard the grid action to return an empty result (or NotFound) instead of throwing for a missing configuration.
  3. Ensure the configuration is created before navigating to its custom-events tab.

Example fix

// before
var configuration = await _facebookPixelService.GetConfigurationByIdAsync(searchModel.ConfigurationId)
    ?? throw new ArgumentException("No configuration found with the specified id", nameof(searchModel.ConfigurationId));

// after — graceful empty grid instead of 500
var configuration = await _facebookPixelService.GetConfigurationByIdAsync(searchModel.ConfigurationId);
if (configuration is null)
    return Ok(new { Data = Array.Empty<CustomEventModel>(), RecordsTotal = 0, RecordsFiltered = 0, Draw = searchModel.Draw });
Defensive patterns

Strategy: validation

Validate before calling

var configuration = await _facebookPixelService.GetConfigurationByIdAsync(searchModel.ConfigurationId);
if (configuration is null) return EmptyGrid(searchModel);

Try / catch

try { return await CustomEventList(searchModel); }
catch (ArgumentException ex) when (ex.Message.Contains("No configuration found"))
{ return NotFound(); }

Prevention

When it happens

Trigger: The custom-events grid is loaded for a ConfigurationId that was deleted, never existed, or was passed incorrectly (query string tampering, stale admin link).

Common situations: Admin opens an old bookmarked/tab after the configuration was deleted; concurrent admin deletion while another browses the grid; ConfigurationId of 0 or default sent by a malformed request.
