I have a DD4T .NET web application using the DXA Model Service. The content is published as the DXA R2 data format.

This situation is supported:

Currently I am getting the following error:

2019-03-15 14:38:13,981 INFO  c.s.d.m.s.DefaultPageModelService - Found R2 model while requested DD4T, need to process R2 and convert, request PageRequestDto(publicationId=135, uriType=tcm, path=/index, includePages=INCLUDE, contentType=MODEL, dataModelType=DD4T, expansionDepth=100, depthCounter=com.sdl.dxa.common.dto.DepthCounter@9f) 
2019-03-15 14:38:14,226 ERROR c.s.d.m.s.ConfigService - Exception happened while loading schemas.json, cannot get schemas config, pub ID = 135 
com.sdl.webapp.common.api.content.StaticContentNotFoundException: No binary meta found for: [135] /system/mappings/schemas.json

I am happy that the error is so clear, but as far as I know, the schemas.json is not part of the DXA installation media:

How can I create this page myself?

DXA PublishMappings TBB. That TBB Publishes schema and region mapping information in JSON format.

In DXA if you publish the Publish Settings page with Core (Module Configuration) component then in the background, These binaries are named like schemas.json are getting published and also have that name (excl. file extension) as variant ID to Broker DB.

In your case, I think you have to create Publish Settings page with the module configuration component and to publish the page so that you will be able to get the schemas.json

I hope it helps.
