How to access different Storefront API versions?

Hello,

The documentation states very clearly that the route should look like this:

For the GraphQL endpoint, enter https://

Unfortunately when using any version specific endpoint, such as this

"https://be-xu.myshopify.com/api/2020-10/graphql"

The browser issues the following errors

When using the following route, however, everything works fine.

"https://be-xu.myshopify.com/api/graphql"

Any help would be greatly appreciated.

Try https://{{ store }}.myshopify.com/api/2020-10/graphql.json
