Solutions

1. Inspect the console.error output to see the real converter error.
2. Re-export from Insomnia using a supported version and the standard export action.
3. Strip unsupported resource types from the export before importing.
4. Update @usebruno/converters to the latest version and retry.

if (!isInsomniaCollection(data)) {
  throw new Error('Not a recognized Insomnia export');
}

function isInsomniaCollection(data) {
  if (typeof data?.type === 'string' && data.type.startsWith('collection.insomnia.rest/5')) {
    return Array.isArray(data.collection);
  }
  if (data?._type === 'export') {
    return Array.isArray(data.resources) && typeof data.__export_format === 'number';
  }
  return false;
}

try {
  convertInsomniaToBruno(data);
} catch (err) {
  console.error('Original converter error:', err);
  throw err;
}

When it happens

Trigger: Passing data that isInsomniaCollection accepted but the converter cannot transform — e.g. an Insomnia v4/v5 export with missing required fields (method, URL, parentId), unknown resource types, or unsupported Insomnia features.

Common situations: Insomnia export from a much older/newer version than the converter supports, exports relying on plugin/gRPC/websocket entries the converter ignores, or partially-edited export files.
