After successfully deploying a subgraph via The Graph to Mumbai it suddenly stops working for no apparent reason

Question

so I have succesfully deployed a subgraph to a fork of the masterchef contract from sushiswap. Before beeing able to sync up properly, the subgraph suddenly throws an error and stops. The error message states:

Subgraph instance failed to run: A matching Ethereum network with NodeCapabilities { archive: true, traces: true } was not found.

That is very odd to me, there is no { archive: true, traces: true } in my subgraph aswell as mumbai beeing written properly in my subgraph.yaml. I cannot figure out how to make my subgraph run succesfully on mumbai testnet. Can anyone help me with that error, since I havent found a good solution on the internet to that problem.

For additional information here is my subgraph.yaml file:
