无法在石墨烯测试中使用字符串化 JSON

Question

I'm trying to write a test that takes in a stringified json value for one of my fields (questionData) and it's failing:

I wrote the mutation like this:

        query = '''mutation {
            createScorecard(
                name: "Test Scorecard",
                creatorId: 395549257913,
                questionData: "[{\"title\":\"This is a test question\",\"description\":\"Test question description\",\"answers\":[{\"text\":\"Yes\",\"point\":50,\"autofail\":true},{\"text\":\"No\",\"point\":50,\"autofail\":false}]}]"
            ) {
                scorecard {
                    name
                }
                error
            }
        }'''

But i keep getting this error:

{'errors': [{'message': 'Syntax Error GraphQL (5:40) Expected :, found String ":"\\n\\n4: creatorId: 395549257913,\\n5: questionData: "[{"title":"This is a test question","description":"Test question description","answers":[{"text":"Yes","point":50,"autofail":true},{"text":"No","point":50,"autofail":false}]}]"\\n ^\\n6: ) {\\n', 'locations': [{'line': 5, 'column': 40}]}]}

Need to use double backslashes when escaping the string
