Failed to export ${environmentType} environments.

Error message

Failed to export ${environmentType} environments.

What it means

Thrown by exportBrunoEnvironment (bruno-environment.js:22). It wraps the renderer:export-environment IPC call; any rejection (unwritable filePath, missing directory, ENOSPC, IPC channel error, or an environment object that fails JSON serialization) is caught and re-thrown as a generic 'Failed to export <environmentType> environments.' message — the original cause is discarded (only console.error retains it).

Solutions

1. Validate filePath is within a writable directory before invoking export (pre-check with fs.access via IPC or a known downloads dir).
2. Validate each environment object shape (name, variables array) before mapping/cleaning.
3. Preserve the underlying cause: throw new Error(msg, { cause: error }) so callers and logs see the real failure.
4. Surface error.message (which already loses detail) — better, return the original IPC error text.

Example fix

// before
catch (error) {
  console.error(`Error exporting ${environmentType} environment as .json:`, error);
  throw new Error(`Failed to export ${environmentType} environments.`);
}

// after
throw new Error(`Failed to export ${environmentType} environments.`, { cause: error });
// caller (ExportEnvironmentModal) already does toast.error(error.message || 'Failed to export environments')

// validate environment shape + filePath before exporting
const isValidEnvironment = (e) =>
  e && typeof e.name === 'string' && Array.isArray(e.variables);

if (!environments.every(isValidEnvironment)) {
  throw new Error('One or more environments are malformed');
}
if (!filePath || typeof filePath !== 'string') {
  throw new Error('A valid export location is required');
}

const isExportableEnvironment = (e) =>
  typeof e?.name === 'string' && e.name.trim().length > 0 && Array.isArray(e.variables);

try {
  await exportBrunoEnvironment({ environments, environmentType, filePath, exportFormat });
} catch (e) {
  // e.message is generic; check console for the original IPC error
  toast.error(e.message || 'Failed to export environments');
}

When it happens

Trigger: renderer:export-environment rejects because filePath points to a read-only/protected directory, a non-existent parent folder, a disconnected drive, or the disk is full; or an environment object contains a non-serializable value (function, circular ref).

Common situations: User picks a system-protected save location; exporting to a network mount that dropped; very large environment sets; filePath unset/invalid despite the modal guard.
