Cancelled

Error message

Cancelled

What it means

When provisioning observability in interactive mode, the CLI shows a project picker via @clack/prompts. This error is thrown when the user cancels the picker (Esc/Ctrl-C), aborting provisioning.

Solutions

Select an existing project or '+ Create new project' instead of cancelling.
Run in a non-interactive mode by supplying the project name/flags so no prompt is shown.
If running in CI, ensure a TTY or use flag-based provisioning to avoid the interactive picker.
Catch the 'Cancelled' error in wrappers around init and exit gracefully with code 0.

Defensive patterns

Strategy: try-catch

Validate before calling

const isInteractive = process.stdout.isTTY;
if (!isInteractive) {
  // use flag-based provisioning to skip the picker
}

Try / catch

try {
  await provisionObservabilityProject(options);
} catch (err) {
  if (err.message === 'Cancelled') {
    process.exit(0); // user aborted; exit gracefully
  }
  throw err;
}

Prevention

Run init in a TTY-enabled terminal.
Use flag-based/non-interactive provisioning in CI.
Don't press Esc/Ctrl-C at the project picker unless aborting intentionally.

When it happens

Trigger: Running `mastra init` observability provisioning, and pressing Esc or Ctrl-C at the 'select a project' prompt when projects already exist in the organization.

Common situations: Developers abandoning init midway, CI environments where no TTY is available so the prompt is auto-cancelled, or users without permissions choosing to abort.
