Electrum: [Synchronizer] cannot deserialize transaction, skipping

[tudorconstantin]

The transaction which can not be deserialized is this e9933221a150f78f9f224899f8568ff6422ffcc28ca3d53d87936368ff7c4b1d, which looks like this serialized:

Because the TX is skipped, the addresses that belong to my wallet involving that tx show as having a balance of zero and I can't get the funds out of them.

I'm using Electrum 3.0.2, but was able to reproduce it in 3.0.5.

As a quick hack, I replaced the empty return from this line with return [m, n, None, None, None], but that is not quite a fix, although it seems to work for me for now.

I tried to debug the issue, but got lost in the bitcoin and segwit protocol.

Btw can you tell us who sent this txn (in broad terms)? E.g. if an exchange, which one; if some type of user-wallet, which one.

[SomberNight]

Based on https://github.com/spesmilo/electrum/issues/3798 it looks like Bitpanda is making these txns.
@ecdsa Should we do a new release?

[tudorconstantin]

Unfortunately I don't have any info regarding who created the transaction and what wallet he used to do it.

I was affected by this as well, but 7b8b75c7d39df2c44ebea30d1362372be830775d seems to be working and fixes the issue for me.

[SomberNight]

Note: 3.0.6 was released yesterday, and that should include the relevant fix.

Another user hit, but this is not (yet) an electrum user, but a Ledger one:

Will try to ping Ledger to fix this on their software also.
