I am using the following code:

const GQL_ADD_JOB = gql`
    mutation AddJob {
        addJob(title: $title, company: $company, description: $description) {
            title
            company
            description
        }
    }
    `;

And then using axios, I attempt to POST using GraphQL's print function:

request.post(
  GQL_ENDPOINT,
  {
    query: print(GQL_ADD_JOB),
    variables: {
      title: job.title,
      company: job.company,
      description: job.description,
    },
  }
)

Where job.title, job.company, and job.description can all be strings containing any character, including newlines, quotes, etc. However, calling this results in a JSON parse error. The error shows that the request sent the following data:

'{"query":"mutation AddJob {\n addJob(title: $title, company: $company, description: $description) {\n title\n company\n description\n }\n}","variables":{"title":"Route Service Sales Representative - 3rd Shift","company":"Cintas","description":"test desc"}}'

When I use this data and manually perform a POST via curl, I get the following error:
