swalkinshaw - thanks for your reply.
Unfortunately, I am still stuck.
What you saw in the logs is that I performed many tests using 2021-04,
2021-07, and even the unreleased 2021-10 endpoints .
I did see your change from valueType to type in 2021-07.
Unfortunately, in using either 2021-07 and 2021-10, my product and variant
are only created if I eliminate the metafield objects.
Thanks for your help, again. If you are truly stumped at your end, please
let me know and I will close out this ticket.
