When testing product import the import fails. After file (link below) loads each of the lines in the file appear to be fine for importing - each line has a green tick and reads fine. However the top level status says that no products can be imported.
Tried the same file (with necessary changes to enterprise name and category) on UK production and the import worked fine.
Import should work or give appropriate errors
Import failed with no useful error
1) Specify the file I used this one
2) Enterprise is found fine
3) All products individually show a green tick as though they are good for import. However the status says that all products have an error and cannot be imported.

S2 as a release blocker
Ok, I think this is a pre-existing issue and it only applies to French staging. There's a different config option that's set there, which means all products must have a Tax Category in order to be valid. If you fill in the tax_category column the import is successful. It's odd that no validation message is shown though.
Notes:
tax_category on instances that use that specific config optionThanks Matt. As we removed spree_backend I figured all issues were worth reporting.
I always do release testing on FR staging and had never encountered this so thanks for tracking it down.
Agree it's not a release blocker.
Good to go.
Thanks for bringing this up @lin-d-hop and your notes @Matt-Yorkley.
I came across this at some point, but couldn't explain the behaviour. I've added a note on our Testing Handbook.
Cheers.
