Not importing related elements from CSV with data delimiter

[peteeveleigh]

I'm running an import from a CSV file with a field that contains a pipe delimited list of product slugs. I have set the dataDelimiter to be "|"

An example of the field contents might be

5kg-5kg-gunmetal-micromax-2-grout-micromax-2-grout|5kg-bal-white-micromax-2-grout|5kg-bal-pebble-micromax-2-grout

The intended behaviour is for the slugs to be used to populated a Related Products field but none is being imported.
If I set the field to contain a single slug with no delimiters then that is not imported either.

I can see from the Feed-Me log that the slugs are being split up from the field but then the query being executed to find the matching element is returning no results.

Grouts and Accessories: Search for existing product with query {"status":null,"typeId":["6b6b280a-e92e-462d-bcca-0f06425b7c1b"],"limit":"","where":["=","slug","5kg-bal-pebble-micromax-2-grout"]}

Grouts and Accessories: Found 0 existing products: []

But there is a product with the slug 5kg-bal-pebble-micromax-2-grout and it is of the product type that matches the UUID shown (but should that be the typeId rather than the UUID?)

This site is currently on 3.6.9 so I'm using the latest Feed Me version that is supported, 4.3.6
