GraphQL CDR reports freePBX16

[subbustrato]

Dears,
I need to address a very simple task, getting CDR reports using GraphQL.

I’m using freePBX16 and below the query I’m sending through GraphQL Explorer:

query {
fetchAllCdrs {
edges{node{id}}
}
}

This is the response I receive:
{
“errors”: [
{
“message”: “Internal server error”,
“status”: false
}
]
}

What I’m wrong?

As you can understand I’m not an expert, I’m just started using this interface…your support will be very appreciated, thanks in advance!!
