Connector Response Size Limit

The maximum size for responses from connectors is 30 MB. Beyond this threshold, Hasura will reject the response to ensure optimum performance and data processing. It's important to be mindful of this constraint when making data queries to Hasura's GraphQL API.

To prevent hitting the response size limit, API consumers are encouraged to utilize the limit argument in their queries to avoid over-fetching data from sources via data connectors.

When GraphQL API requests exceed this size limit, they will result in an internal error API response.

{
  "data": null,
  "errors": [
    {
      "message": "internal error"
    }
  ]
}

Hasura users are advised to check the traces for more detailed error information, which includes the actual response size from the connector.
