Invalid environment: expected an object

Error message

Invalid environment: expected an object

What it means

Thrown by validateBrunoEnvironment() at the top of the Bruno environment import pipeline. It fires when the parsed environment value is not a non-null object (it is null, undefined, a primitive, or an array). This is the first structural gate before variables are inspected.

Solutions

1. Open the imported file and confirm the top-level value (or each element of the environments array) is a JSON object with curly braces.
2. If the file is empty or null, regenerate it via Bruno's Export Environment action.
3. Run JSON.parse(content) in a console and verify typeof result === 'object' && result !== null && !Array.isArray(result) before importing.
4. Validate the file against Bruno's environment schema before import.

Example fix

// before: file content is 'null' or '"staging"'
// after: file content is
{
  "name": "Staging",
  "variables": []
}

function isPlainObject(v) {
  return v !== null && typeof v === 'object' && !Array.isArray(v);
}
// before calling importBrunoEnvironment / validateBrunoEnvironment:
if (!isPlainObject(env)) throw new Error('Environment must be a plain object');

function isBrunoEnvironment(env) {
  return env !== null && typeof env === 'object' && !Array.isArray(env);
}

try {
  validateBrunoEnvironment(env);
} catch (err) {
  if (err.message.startsWith('Invalid environment: expected an object')) {
    // surface to user that the file root is not an object
  }
  throw err;
}

When it happens

Trigger: Calling importBrunoEnvironment / processEnvironmentData with a parsed JSON document whose environment entry is null, a string, a number, a boolean, or an array (e.g. a top-level JSON array element that is a primitive, or an empty file parsed to null).

Common situations: Empty or whitespace-only .json file, JSON.parse returning a primitive (e.g. file content is just "true" or "42"), exporting a single environment as a bare array, or hand-editing an environment file so a variable slot is null.
