JSS FormatException: DebugOnly

JSS FormatException: DebugOnly

When Upgrading from JSS tech preview to Sitecore 9.1 with Sitecore JavaScript Services 11.0 I got a Error about my GraphQL endpoint configuration. Or when you use the master GraphQL endpoint example on  https://jss.sitecore.com/ it is easy to fix.

Take the sample from \App_Config\Sitecore\Services.GraphQL

Or change:

 <gui role:require="!ContentDelivery">DebugOnly (follow web.config compilation setting)</gui>

to

 <gui role:require="!ContentDelivery">false</gui>

and this error is gone:

Server Error in '/' Application.

                            Cache improves the query performance by caching parsed queries.
                            It is also possible to implement query whitelisting by implementing an authoritative query cache;
                            WhitelistingGraphQLQueryCache is an example of this, capturing queries to files in open mode and allowing only captured queries in whitelist mode.

                            Extenders allow modifying schema types after they are created by a schema provider but before they are added to the final schema.
                            This is useful when you want to _extend_ a generated schema, for example to add external API
                            data onto the item API, or to add in custom internal data (e.g. custom layout data to power an app)
                            without having to directly modify a schema provider.

                            Extenders must derive from SchemaExtender.
