There were some errors when importing all the descriptors, I don't know why.
The error should indicate what went wrong including errors in the command/args syntax.
In the meantime, I asked "Copilot" and it told me that the command
importdescriptors
also works for addresses
Yes, there's an
addr descriptor to directly import addresses.
But the advantage of using the migrated
combo(pubKey/PrvKey) descriptors is it works the same as your legacy wallet which includes all three script types per key.
Useful for someone who used a lot of addresses of different types.
For reference here are the available descriptors in Bitcoin Core:
