Thanks much.
I have been following fairly the same steps but with the console rather than on the command line.
I am able to get the lambda fields to work, but no luck with query or mutations.
Is there something related to strict mode https://dgraph.io/docs/cloud/admin/schema-modes/ , I am not entirely sure if this has something to do with my “Operations not allowed”. The literature/ notes related to it are hard to understand.
Any insights on what exactly is “operations not allowed - [name of the query/mutation]” ? Any pointers on how can I figure out the issue around lambda fields working , mutations and queries failing ?
