You could try using the GraphQL API instead, which has a mutation for productCreate would look something like:

mutation {
  productCreate(input: {
    title: "Sample Product",
    vendor: "SampleVendor",
    descriptionHtml: "**Description**",
    status: DRAFT,
    productType: "DEFAULT_TYPE",
    templateSuffix: "default_template",
    productOptions: [{
      name: "Option",
      position: 1,
      values: [{name: "Value1"}, {name: "Value2"}]
    }],
    metafields: [{
      namespace: "custom",
      key: "pickers",
      value: "{\"colors\":[{\"title\":\"Color A\",\"material_handle\":\"material1\"},{\"title\":\"Color B\",\"material_handle\":\"material2\"}]}",
      type: "json"
    }]
  }) {
    product {
      id
      title
      status
    }
    userErrors {
      field
      message
    }
  }
}

Hi,

what is the response of your request?

What I am seeing from the screenshot: The tags must be a string with comma separated tags.

All the best,

Michael
