I have no clue, I do not use this input, but searching on the forum I found a similar [post](https://discuss.elastic.co/t/filebeat-pagination-doesnt-support-in-field-name-azure-graphapi/347621).

It seems that the `httpjson` does not suport fields with `@` in the name.

You may need a response from someone from Elastic or maybe open an issue in Github.
