What is the correct way to call doreload via GraphQL?

Running FreePBX 16.0.21.4 with PBX API 16.0.10 (there are no updated via edge).
I’m trying to call doreload via…

mutation {
doreload(input: {}) {
message
status
transaction_id
}
}

As indicated in tutorials and documentation. However this generates an error…

"Cannot query field “doreload” on type “Mutation”

Community posts that mention this offer no resolution for PBX API 16.0.10.

Any ideas? Thanks.

Can anybody help with this?

What happens when you check if a reload is required?

That doesn’t work either…

message: “Cannot query field “fetchNeedReload” on type “Query”.”
status: false
