JSON API MvCall Doubling Data

[K Series Parts]

Wrote a module that takes 3rd party data and imports it into the combo facets using the JSON API. The data all the way to the MVCall is only showing single values but it doubles the results in the combo facets database. It doesn't do it all the time, just for some products and I can't figure out a pattern. Curious if anyone else has had this issue or could provide some insight.

Can you post an example request?

I don't see anything immediately wrong with this. Are you sure the number of engines passed in doesn't have duplicates? You should call log the request made to the API to ensure duplicate values are not being included. Also are you sure you are not calling this function more than 1 time? Calling it multiple times would add duplicate values.

not sure if this was it but I had changed from an assign to an eval in the xml function when I posted this and that seemed to stop it from double importing from my testing so far
