When I try to create a shopify metafield definition I get:
Setting access controls on a definition under this namespace is not permitted
This is the graphql variable:
"definition": {
"description": "mymeta",
"key": "mymeta",
"name": "mymeta",
"namespace": "features",
"ownerType": "PRODUCT",
"pin": True,
"type": "single_line_text_field",
"useAsCollectionCondition": True,
"visibleToStorefrontApi": True
}
