Cannot read properties of undefined (reading 'playground') error when deploying subgraph to https://graphql.xinfin.network

Hello,

I've encountered an issue while deploying a subgraph to the Graph Node with the endpoint https://graphql.xinfin.network. The error message I'm receiving is:
UNCAUGHT EXCEPTION: TypeError: Cannot read properties of undefined (reading 'playground')

I've attached images of the logs for reference. Have you encountered this error before? If so, could you please provide guidance on how to resolve it?
