I tried to run the following query, but it returns

“Field ‘checkoutCreate’ doesn’t exist on type ‘Mutation’”

Can anyone help?

mutation {
checkoutCreate(input: {
lineItems: [{ variantId: “gid://shopify/ProductVariant/37723173093526”, quantity: 1 }]
}) {
checkout {
id
webUrl
lineItems(first: 5) {
edges {
node {
title
quantity
}
}
}
}
}
}

Finally I found the problem.

The URL was incorrect. The storefront API URL does not need /admin/.
