Internal error when mapping Magma collection

When creating an analytics collection on the Magma collection Magma._default._default using DDL

alter collection Magma._default._default enable analytics;

 
the expected error

[

  {

    "code": 22003,

    "msg": "Magma buckets are not supported",

    "query_from_user": "alter collection Magma._default._default enable analytics;"

  }

]

is returned shown.
But when mapping the analytics collection using the "Map from Data Service" wizard, an internal error is reported
