Error in testnet

[SovaSlava]

Hello.

When i create new, or load previously created multisig, I've got error - The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type object

Example - https://multisig.ton.org/?testnet=true#kQDhjTAQuS6w7EnUf94yLa_SO_D7iW2pKJ1eavCsv-6_mTEj
