Error processing ${fileName}: ${err.message}

Error message

Error processing ${fileName}: ${err.message}

What it means

Outer catch-all in processEnvironmentData. Fires when data is neither the new info.type format nor an array, and validateBrunoEnvironment(data) on the single-object path throws (errors 60-63), or when an unexpected exception escapes the inner handlers.

Solutions

1. Check the inner message after 'Error processing <fileName>:' to find the root validateBrunoEnvironment cause.
2. Verify the file is intended as a Bruno environment, not a collection or Postman file.
3. Re-export a known-good environment and diff it against the failing file.

if (!isNewBrunoEnvironmentFile(data) && !Array.isArray(data)) {
  if (!isBrunoEnvironment(data)) throw new Error('Single-object payload is not a valid environment');
}

function isAnyBrunoEnvironmentFormat(data) {
  return isNewBrunoEnvironmentFile(data) || Array.isArray(data) || isBrunoEnvironment(data);
}

try {
  processEnvironmentData(data, fileName);
} catch (err) {
  // surface the inner 'Error processing <file>: <inner>' chain
  throw err;
}

When it happens

Trigger: Passing a single environment object that fails validation, or any non-array/non-bruno-environment payload that hits the fallback return [validateBrunoEnvironment(data)] line and throws.

Common situations: Importing a JSON object that looks like an environment but is malformed, or passing a completely different document type (e.g. a collection) into the environment importer.
