no mutation exists

[linklin830912]

Hi all,
I'm new to hasura, I am setting up hasura with MongoDB according to the instruction here:https://www.mongodb.com/developer/products/atlas/graphql-apis-hasura/
While query works, I'm not sure why there's no mutation option in the interface:

also when I wrote a mutation manually, it shows:

is there any possible solutions?
Thanks

Hi @linklin830912 - The MongoDB connector for Hasura v2 only supports queries.

We recommend upgrading to Hasura DDN and use the latest Mongo Connector to try out mutations. The tutorial you see on MongoDB will be updated soon with the change to Hasura DDN.
