Unterminated string

[lucasantoniooficial]

is giving this error: String not terminated.

I can't find the way out, I have another upload code that works and this one, because it has more data, isn't working.

`const formData = new FormData();
const blob = new Blob([fs.readFileSync(files.thumbnail[0].filepath)])

            formData.set("operations", JSON.stringify({
                query: `
                    mutation CourseCreate($thumbnail: Upload! $teacherIds: [Int]!) {
                        courseCreate(
                            course_category_id: ${fields.course_category_id[0]},
                            teacher_ids: $teacherIds,
                            thumbnail: $thumbnail,
                            name: "${fields.name[0]}",
                            description: "${fields.description[0]}",
                            short_description: "${fields.short_description[0]}",
                            price: "${fields.price[0]}",
                            difficulty: "${fields.difficulty[0]}",
                            status: "Pendente"
                        ) {
                            id
                        }
                    }
                `,
                variables: {
                    "thumbnail": null,
                    "teacherIds": [fields.teacher_ids[0]]
                }
            }));

            formData.set('map', JSON.stringify({
                thumbnail: ["variables.thumbnail"],
                teacherIds: ["variables.teacherIds"]
            }));

            formData.append('thumbnail', blob);

            const {data} = await httpGraphql(formData, null, token, {
                "Content-Type": "multipart/form-data"
            });

            console.log(data);`
