Same issue with Version 1.0 alpha 21 and latest multichain-explorer.

Please add this to Mce/DataStore.py at line 1614:

txout['address_version'] = None

So the start of the function should look like this:

    def _export_scriptPubKey(store, txout, chain, scriptPubKey):
        """In txout, set script_type, address_version, binaddr, and for multisig, required_signatures."""

        if scriptPubKey is None:
            txout['script_type'] = None
            txout['binaddr'] = None
            txout['address_version'] = None
            return

Restart the explorer. Does this fix the issue?

If not, insert a debug statement at line 1167 of Mce/abe.py, and send me the output of the tx causing the exception.

    print ">>> tx = ", row
    if row['address_version'] is chain.script_addr_vers:

Thanks.

It fixes the issue. Thanks a lot for figuring this out.
