This might be the wrong place to ask but:
I have created an unsigned segwit transaction on electrum
010000000001016ce640462fb3302c40be33209eafb1c3088ebf6090a4c6d569bbaf3a2c72cb1d0000000000fdffffff02904d00000000000016001459a5efe7f6e80e338dd56c5f4f849f8464888eb2905f0100000000001976a91453c1d05822e2658fd2e1ce0c88184fd3234b081688acfeffffffffb0ad0100000000000201ff53ff045f1cf60122ac17c880000000f70edd475d43567f91ae697de230e82d45adb4b61cf40ad236882898a291ffb602c07ea35af414345f3c92edd9bb114438cc33d71598c64655c7c26318bd0b692b000000008a271400
Which Electrum deserialises as:

}
but this library finds that hex invalid.
If I comment out the deserialisation error (new Error("Incomplete tx deserialization"))
then btcnodejs produces a transaction similar with the the witness hex of
ffffffb0ad0100000000000201ff53ff045f1cf60122ac17c880000000f70edd475d43567f91ae697de230e82d45adb4b61cf40ad236882898a291ffb602c07ea35af414345f3c92edd9bb114438cc33d71598c64655c7c26318bd0b692b000000008a271400
I'm guessing this is because when Electrum deserialize the transaction it knows that the witness is not that long (yet). Have you any interest (or idea how) to deserialize partially signed electrum transactions?
For completeness the signed transaction hex is
010000000001016ce640462fb3302c40be33209eafb1c3088ebf6090a4c6d569bbaf3a2c72cb1d0000000000fdffffff02904d00000000000016001459a5efe7f6e80e338dd56c5f4f849f8464888eb2905f0100000000001976a91453c1d05822e2658fd2e1ce0c88184fd3234b081688ac02483045022100ebeb625c62d618c097fb1d54fef8bd3f57698bac191adca0a552725e4f577afc022001814513b04c272c5c86c4a37dd55700be543dc5732db5176dce377f954bd884012103f5b78846b3420430e455df568e4bee061827704c36163699544a0e60660fb7cb8a271400
And here then I can deserialize using btcnodejs and I get the correct witness hex:
btcnodejs witness hex:
3045022100ebeb625c62d618c097fb1d54fef8bd3f57698bac191adca0a552725e4f577afc022001814513b04c272c5c86c4a37dd55700be543dc5732db5176dce377f954bd8840103f5b78846b3420430e455df568e4bee061827704c36163699544a0e60660fb7cb
electrum witness hex is:
02483045022100ebeb625c62d618c097fb1d54fef8bd3f57698bac191adca0a552725e4f577afc022001814513b04c272c5c86c4a37dd55700be543dc5732db5176dce377f954bd884012103f5b78846b3420430e455df568e4bee061827704c36163699544a0e60660fb7cb
Here is the result of
btcnodejs.Transaction.fromHex("010000000001016ce640462fb3302c40be33209eafb1c3088ebf6090a4c6d569bbaf3a2c72cb1d0000000000fdffffff02904d00000000000016001459a5efe7f6e80e338dd56c5f4f849f8464888eb2905f0100000000001976a91453c1d05822e2658fd2e1ce0c88184fd3234b081688acfeffffffffb0ad0100000000000201ff53ff045f1cf60122ac17c880000000f70edd475d43567f91ae697de230e82d45adb4b61cf40ad236882898a291ffb602c07ea35af414345f3c92edd9bb114438cc33d71598c64655c7c26318bd0b692b000000008a271400")Transaction {
