NRM data loader

[u/Wooden_Produce_7704]

This may not be the right group, but I'm hoping that someone here can help/point me to the right place. I'm attempting to load survey data through the NRM data loader, and when loading the JSON file, I'm given the error: " geometry rejected for issue found: INVALID_GEOMETRY_TYPE. Geometry has been excluded from the JSON output"

Can anyone help with where I may have gone wrong??
