Help with Error when applying schema when API returns null records

[JoeFields]

I am getting errors on Record type objects when I try to apply a schema in my custom connector even though I have added the nullable type identifier in the schema.

The below example shows whenever I have location = null, it throws an error.

Here is a condensed listing of how I am defining my schema in my PQ file:

ProjectType = type table [
...
    location = nullable LocationType,
...],
    LocationType = type [
        country = text,
        state = text,
        streetName = text,
        streetNumber = text,
        suite = text,
        city = text,
        zip = text,
        complete = text,
        coords = nullable CoordsType
    ]

I have defined location as being a nullable record.

I copied the Table.ChangeType helper function from here: https://learn.microsoft.com/en-us/power-query/helper-functions#tablechangetype. I also have been following the TripPin examples to build out my connector.

If I change the schema definition to nullable any then it works but then I do not have my schema applied for the location records that are provided.

ProjectType = type table [
...
    location = nullable any,
...],

The REST API I am connecting to sometimes has the location records filled in but sometimes location is just null as in the below examples:

I can't figure out where in the Table.ChangeType helper function I can make a tweak to cover the null record conditions but I would have thought making it nullable would have done the trick. Any thoughts?

This appears to be similar to this previous unanswered post from a few years ago: https://community.fabric.microsoft.com/t5/Power-Query/Error-with-nullable-record-type-when-using-Tab...
