File Upload with GraphQL not working

My Code in the GraphQL Playground:

The upload is not working. I always get an Error like this:

“error”: {
“errors”: [
{
“message”: “Variable “$file” got invalid value { url: “https://onlinejpgtools.com/images/examples-onlinejpgtools/sunflower.jpg” }; Upload value invalid.”,
