Graph QL syntax error at metafield value, list type

I’m recieving a syntax error when trying to update a metafield created in the shopify admin on productCreate mutation. I have tried formatting the value in every way imaginable, and still recieves an error.

This is my mutation:

`mutation {
      productCreate(input: {
        title: "example title",
        handle: "example-title",
        descriptionHtml: "just an example", 
        productType: "my type", 
        tags: ["tag1,tag2"],
        variants:{
          price: "100",
          sku: "123",
        },
        metafields: [
          {
            id: "gid://shopify/Metafield/<id>",
            namespace: "custom",
            key: "key_example",
            type: "list.single_line_text_field",
            value: "[\"test1\",\"test2\"]"
          }
        ],
      }) {
        product {
          id
          variants(first:1){
            edges{
              node{
                id
              }
            }
          }
        }
        userErrors {
          message
          field
        }
      }
    }`

And this is the error I recieve:

GraphqlQueryError: syntax error, unexpected STRING (“,”), expecting COLON at [19, 28]

Also after trying to format the value like this:

value: "['test1','test2']"

I get a response on the userErrors:

{“product”:null,“userErrors”:[{“message”:“Value is invalid JSON: unexpected token at ‘‘test1’,‘test2’]’.”,“field”:[“metafields”,“0”,“value”]}]}

Is there anyone that have met the same problem, or is a graphql expert that can help me? :blush:

Have you tried escaping the backslash in the value?

{
            id: "gid://shopify/Metafield/<id>",
            namespace: "custom",
            key: "key_example",
            type: "list.single_line_text_field",
            value: "[\\"test1\\",\\"test2\\"]"
          }

I’ve spent several hours getting a metaobject with a rating field type to work. I ended up with the following;

{
  key: "rating",
  value: "{\\"scale_min\\":0,\\"scale_max\\":5,\\"value\\":3}"
},
