Hi there, can you share the code that you used to try the API?

Also I have a direct API on Rapid: https://rapidapi.com/oneapiproject/api/skip-tracing-working-api/

Let me know, how can I help. Thanks.

Hi, I was able to fix the issue.

Please try now and let me know the results. Thanks!

Thanks. Will try today. I am making a endpoint where users can upload a excel or csv list of contact and then cleaning it up to send to your endpoint.

Here is my code if it helps at all.

[ApiExplorerSettings(IgnoreApi = true)] [HttpPost("run")] [Consumes("multipart/form-data")] public async Task<ActionResult> RunMapped( [FromForm] IFormFile file, [FromForm] FieldMappingRequest mapping) { try { _logger.LogInformation("Starting mapped skip trace run: File: {FileName}", file?.FileName);

if (file == null || file.Length == 0)
       {
           _logger.LogWarning("Mapped skip trace rejected: No file or empty file provided");
           return BadRequest("No file provided or file is empty.");
       }

       if (!IsValidFileExtension(file.FileName))
       {
           _logger.LogWarning("Mapped skip trace rejected: Invalid file type: {FileName}", file.FileName);
           return BadRequest("Invalid file type. Only CSV and XLSX files are supported.");
       }

       if (!IsValidMapping(mapping))
       {
           _logger.LogWarning("Mapped skip trace rejected: Invalid column mapping");
           return BadRequest("Invalid column mapping. Required fields must be mapped to columns.");
       }

       // Build the map: DTO property name → column header name
       var columnMap = new Dictionary<string, string>
       {
           ["FirstName"] = mapping.FirstNameColumn,
           ["LastName"] = mapping.LastNameColumn,
           ["StreetAddress"] = mapping.StreetColumn,
           ["City"] = mapping.CityColumn,
           ["State"] = mapping.StateColumn,
           ["ZipCode"] = mapping.ZipColumn,
       };

       // Parse into your AddressDto list
       var rows = await _files.ParseAddressesAsync(
           file.OpenReadStream(),
           file.FileName,
           columnMap
       );

       if (rows == null || !rows.Any())
       {
           _logger.LogWarning("Mapped skip trace: No valid addresses found in file {FileName}", file.FileName);
           return BadRequest("No valid addresses found in the file.");
       }

       _logger.LogInformation("Parsed {Count} addresses from file {FileName}", rows.Count(), file.FileName);

       // Kick off skip‑trace by raw addresses
       var activity = await _skip.StartSkipTraceByAddressesAsync(rows, OrgId);

       _logger.LogInformation("Skip trace activity created: {ActivityId} with {Count} addresses",
           activity.Id, rows.Count());

       return CreatedAtAction(nameof(GetById), new { id = activity.Id }, activity);
   }
   catch (FormatException ex)
   {
       _logger.LogError(ex, "Format error parsing file {FileName}", file?.FileName);
       return BadRequest($"Error parsing file: {ex.Message}");
   }
   catch (Exception ex)
   {
       _logger.LogError(ex, "Error running mapped skip trace: {FileName}", file?.FileName);
       return StatusCode(500, "An error occurred while processing your request. Please try again.");
   }

}

///

if (contactIds == null || contactIds.Length == 0)
       {
           _logger.LogWarning("Skip trace rejected: No contact IDs provided");
           return BadRequest("No contact IDs provided.");
       }

       // This is a more direct method that does both steps in one call
       var activity = await _skip.StartSkipTraceAsync(contactIds, OrgId);

       _logger.LogInformation("Skip trace activity created: {ActivityId} for {Count} contacts",
           activity.Id, contactIds.Length);

       return CreatedAtAction(nameof(GetById), new { id = activity.Id }, activity);
   }
   catch (Exception ex)
   {
       _logger.LogError(ex, "Error starting skip trace for {Count} contacts", contactIds?.Length ?? 0);
       return StatusCode(500, "An error occurred while processing your request. Please try again.");
   }

}

Can you please recheck now? I just added a fix.
