Invalid issue id/number

Error message

Invalid issue id/number

What it means

IssueChoiceInput converts input strings into issue ids (Long). A single non-numeric value cannot be parsed by Long.valueOf, and the NumberFormatException is rethrown as ValidationException('Invalid issue id/number').

Solutions

1. Enter the numeric issue id/number only (42, not #42).
2. Use the issue picker UI for the input instead of manual entry.
3. Fix the job spec default value so its ${...} substitution resolves to a numeric issue id.
4. Verify the referenced issue exists in the project.

Example fix

// before
value: "#42"
// after
value: "42"

// Numeric issue id check before submitting
if (!/^\d+$/.test(String(issueValue).replace(/^#/, ""))) {
  throw new Error("Issue reference must be a numeric id/number");
}

boolean isNumericIssueRef(Object v) {
  return v instanceof String && ((String) v).replaceFirst("^#", "").matches("\\d+");
}

try {
    Object issue = IssueChoiceInput.convertToObject(strings);
} catch (ValidationException e) {
    // show "enter numeric issue id" hint
}

When it happens

Trigger: convertToObject receives one string for an issue-choice input that is not a valid number (e.g. a string with '#', letters, or a partial issue title).

Common situations: Typing '#42' or an issue key instead of the numeric id; a default value template that failed to resolve and passed through literal text; copying a value from a URL that contained extra path segments.
