Error in Deluge script, but all should be OK

Error in Deluge script, but all should be OK

I get an error when using the following deluge script (sensitive info changed with ***).

This script should parse a projectnumber out of the subject or body text and put it in a custom field of the ticket.

The error:
Validation failed for the condition : Syntax error. Expecting ']' or invokeurl parameter values. Found ','.. LineNumber : 10

The code:
  1. // Validate ticketId (numeric)
  2. if (ticketId == null) {
  3.     info "Error: ticketId is null"; 
  4.     return;
  5. }

  7. // Fetch ticket details
  8. try {
  9.     ticketDetails = invokeurl [
  10.         url: "https://***.nl/api/v1/tickets/" + ticketId,
  11.         type: GET,
  12.         connection: "myapi"
  13.     ];
  14. } catch (e) {
  15.     info "Fetch ticketDetails Error: " + e;
  16.     return;
  17. }

  19. // Fetch latest thread
  20. try {
  21.     threadDetails = invokeurl [
  22.         url: "https://***.nl/api/v1/tickets/" + ticketId + "/latestThread?include=plainText",
  23.         type: GET,
  24.         connection: "myapi"
  25.     ];
  26. } catch (e) {
  27.     info "Fetch threadDetails Error: " + e; 
  28.     return;
  29. }

  31. // Extract content and initialize
  32. ticketSubject = ticketDetails.get("subject"); 
  33. ticketBody = threadDetails.get("plainText"); 
  34. projectNumber = ""; 

  36. info "Subject/Body: " + ticketSubject + " | " + ticketBody;

  38. // Search in subject for B + 5 digits
  39. if (ticketSubject != null && ticketSubject != "" && ticketSubject.length() >= 6) {
  40.     len = ticketSubject.length();
  41.     maxStart = len - 6;
  42.     for idx = 0; idx <= maxStart; idx = idx + 1 {
  43.         candidate = ticketSubject.substring(idx, idx + 6);
  44.         if (candidate.substring(0,1).toUpperCase() == "B" && candidate.substring(1,6).matches("\\d{5}")) {
  45.             projectNumber = candidate;
  46.             break;
  47.         }
  48.     }
  49. }

  51. // If not found in subject, search in body
  52. if (projectNumber == "" && ticketBody != null && ticketBody != "" && ticketBody.length() >= 6) {
  53.     len = ticketBody.length();
  54.     maxStart = len - 6;
  55.     for idx = 0; idx <= maxStart; idx = idx + 1 {
  56.         candidate = ticketBody.substring(idx, idx + 6);
  57.         if (candidate.substring(0,1).toUpperCase() == "B" && candidate.substring(1,6).matches("\\d{5}")) {
  58.             projectNumber = candidate;
  59.             break;
  60.         }
  61.     }
  62. }

  64. info "projectNumber: " + projectNumber;

  66. // Update custom field if found
  67. if (projectNumber != "") {
  68.     customFieldsMap = Map(); 
  69.     customFieldsMap.put("cf_b_nummer", projectNumber);
  70.     updateData = Map(); 
  71.     updateData.put("customFields", customFieldsMap);

  73.     try {
  74.         invokeurl [
  75.             url: "https://***.nl/api/v1/tickets/" + ticketId,
  76.             type: PATCH,
  77.             headers: {"Content-Type":"application/json"},
  78.             parameters: updateData,
  79.             connection: "myapi"
  80.         ];
  81.         info "Project number updated successfully";
  82.     } catch (e) {
  83.         info "Update Error: " + e;
  84.     }
  85. }
Somebody knows where to look? I really don't understand whats wrong with the script. The invokeurl is correctly formatted.
