Reproducible By

I’m using mercurios.

my mutation is:

mutation uploadReimbursementAttachment($reimbursementAttachmentInput: ReimbursementAttachmentInput!) {
  uploadReimbursementAttachment(reimbursementAttachmentInput: $reimbursementAttachmentInput){
    id,
    name, 
    path
  }
}

reimbursementAttachmentInput is:

{
    "reimbursementAttachmentInput": {
    "id": "1cc040bd-eb68-4fac-8d45-11caa369ac3e",
    "policyId": "123456",
    "clientCodeCore" : "0000012349999",
    "name": "medicine-invoice1.jpg",
    "mimeType": "image/jpg",
    "attachments": "base64 string" // => add base64 image
  }
}

create task runner with postman with 5 to 10 request

Environment

alpine image node v14.16.1

Additional context

it is my fetch function

export const fetch = async (url: string, options: Client.RequestOptions) => {
  const client = new Client(url);
  const response = await client.request(options);
  let data = '';
  for await (const chunk of response.body) {
    data += String(chunk);
  }

  client.close();
  return { ...response, body: data };
};

Correct. Maybe let’s create a DanglingResponseError?

Yea I guess that wouldn’t hurt. But in the case of pipelining this is impossible to detect.

[mcollina]

I’ll fix it 😃.
