Research direction

Start a fresh node in regtest mode and run getnewaddress followed by getaddressinfo, comparing the generated bech32 address with legacy and p2sh-segwit results. Trace the address parsing and validation path for regtest and add coverage for this reproduction; done means getaddressinfo returns address information instead of Invalid address.

Written by the indexing model from the issue text.

Description

Expected behavior

When calling getnewaddress and then getaddressinfo on the newly generated address, it should work and return the address info, not an error.

Actual behavior

getaddressinfo returns:

error code: -5
error message:
Invalid address

but only for bech32 addresses and apparently only in regtest chain. Legacy and p2sh-segwit seems to work fine.

To reproduce

Just starts a fresh node in regtest mode, and type the 2 commands.
