Thank you all! I got it working and I learned a lot in the process – inspecting the changeset with IO.inspect() was helpful because I could see the diffs and where fields were being included in or omitted from the changeset. I ran into a bit of trouble because I had set a default value for country, so that would cause that key to be missing from the changeset. Similarly, with the optional “street2” value, if it was sent with a blank value or omitted entirely, the changeset would end up without that field.
