I am checking if primary key has a conflict and then replace all values with new ones.

And i have array of maps that i want to insert through insert_all Repo function.

But i want to use on_conflict option to replace_all fields if conflict occurs on room_id(primary_key) like this:

  Repo.insert_all(schema_name, list_of_maps,  on_conflict: :replace_all, conflict_target: [:room_id], returning: true)

Here are my list of maps

[
%{
"date_from" => #DateTime<2016-11-03 13:23:00Z>,
"date_to" => #DateTime<2016-11-03 13:23:00Z>,
"room_id" => 8,
"unit_id" => 11
},
%{
"date_from" => #DateTime<2016-11-03 13:23:00Z>,
"date_to" => #DateTime<2016-11-03 13:23:00Z>,
"room_id" => 9,
"unit_id" => 11
}
]

But it returns internal server error in test cases without any helpful stacktrace.

Any suggesstions?
Thanks

Please provide the stacktrace anyway.
