Problem

Issue 1: Workspace Not Connected Error Dialog

When importing a workflow from Slack, if the source workspace is not connected, users saw an error without clear guidance on what to do next.

Issue 2: Missing OAuth Scope

Importing workflows from workspaces other than cc-wf-studio failed with permission errors because the files:read scope was missing from OAuth authentication.

Error observed:

{
  "error": "missing_scope",
  "needed": "files:read",
  "provided": "chat:write,files:write,channels:read,groups:read"
}

Solution

Fix 1: Add SlackConnectionRequiredDialog

• Created new dialog component to prompt users to connect to the source workspace
• Display workspace name (Base64 encoded in deep links) for clear identification
• Added i18n translations for 5 languages (en, ja, ko, zh-CN, zh-TW)

Fix 2: Add files:read OAuth Scope

• Added files:read to required OAuth scopes in slack-oauth-service.ts
• This enables downloading workflow files from any connected workspace

Changes

New Files

• src/webview/src/components/dialogs/SlackConnectionRequiredDialog.tsx

Modified Files

• src/extension/services/slack-oauth-service.ts - Added files:read scope
• src/extension/commands/slack-share-workflow.ts - Pass workspaceName through flow
• src/extension/commands/slack-import-workflow.ts - Handle WORKSPACE_NOT_CONNECTED error
• src/extension/utils/slack-message-builder.ts - Add workspaceName to deep links
• src/extension/utils/slack-error-handler.ts - Add workspaceId to error info
• src/shared/types/messages.ts - Add workspaceName to payload types
• src/webview/src/App.tsx - Handle error and show dialog
• i18n translation files (5 languages)

Impact

• Users can now see which workspace they need to connect when importing fails
• Workflow import from other workspaces now works after re-authenticating with Slack
• Note: Existing users must re-authenticate with Slack to get the new files:read scope

Testing

• Manual E2E testing completed
• Code quality checks passed (format, lint, check, build)
