Internal server error bulkOperationRunMutation

[PostCreator]

Hi, I'm getting the following error when running a bulkOperationRunMutation:

{
  "errors": [
    {
      "message": "Internal error. Looks like something went wrong on our end.\nRequest ID: 69d74423-26d7-4140-8617-efc5ef72f94b (include this in support requests).",
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR",
        "requestId": "69d74423-26d7-4140-8617-efc5ef72f94b"
      }
    }
  ]
}

I've used this mutation:

mutation {
  bulkOperationRunMutation(
    mutation: "mutation call($input: ProductInput!) { productCreate(input: $input) { product {id title variants(first: 10) {edges {node {id title inventoryQuantity }}}} userErrors { message field } } }",
    stagedUploadPath: "tmp/56022990931/bulk/783c56ea-264b-40c4-9bd7-0a996a471eeb/bulk10.jsonl") {
    bulkOperation {
      id
      url
      status
    }
    userErrors {
      message
      field
    }
  }
}

 Could it be that I've made a mistake in the mutation? I wasn't able to find an answer in the other topics.
