AI Triage Analysis

Component: Workflow Name Validation | Priority: P3 | SKU: Standard (Portal)

Relevant Code

• libs/designer/src/lib/core/templates/utils/helper.ts:273-283 — checkWorkflowNameWithRegex(): validates against /^[A-Za-z][A-Za-z0-9]*(?:[_-][A-Za-z0-9]+)*$/ and returns error message
• libs/designer/src/lib/core/actions/bjsworkflow/templates.ts:392 — Calls checkWorkflowNameWithRegex() during workflow creation
• libs/designer/src/lib/ui/templates/basics/singleworkflow.tsx — Template workflow name input UI
• libs/designer/src/lib/ui/templates/basics/multiworkflow.tsx — Multi-workflow name input UI

Probable Root Cause

The current validation error message is: "Workflow name must start with a letter and can contain letters, numbers (0-9), dashes (-), and underscores (_)." This is defined at helper.ts:277. While technically accurate, it does not explicitly call out that spaces are not allowed, which is the specific case the reporter hit. Users typing a natural name like "My Workflow" get a generic regex-failure message without clear guidance about spaces.

However, this error message may not be the one shown in the Portal. The screenshots suggest the Portal may display a different (less helpful) error message from its own validation layer, separate from the UX repo validation. The Portal-side workflow creation may have its own name validation that produces a less descriptive error.

Suggested Investigation

1. Check whether the Portal has separate workflow name validation that produces a different error than what is in this repo
2. Consider making the error message explicitly mention that spaces are not allowed — e.g., "Workflow name cannot contain spaces. It must start with a letter and can contain letters, numbers, dashes, and underscores."
3. The regex at helper.ts:274 correctly rejects spaces — the fix is purely about error message clarity
