How do I serialize TransactionBuilder

I need several nodes to build one transaction. To achieve that I create a TransactionBuilder and pass it to nodes that then add their states to it.

This seems to be a legit practice since the official documentation mentions [TransactionBuilder] is intended to be passed around contracts that may edit it by adding new states/commands.

However when running a unit test the network throws this exception:

Class class net.corda.core.transactions.TransactionBuilder is not on the whitelist or annotated with @CordaSerializable. java.io.NotSerializableException: Class class net.corda.core.transactions.TransactionBuilder is not on the whitelist or annotated with @CordaSerializable.

I tried white-listing TransactionBuilder, but the it threw this:

net.corda.core.transactions.TransactionBuilder -> outputs(java.util.List<net.corda.core.contracts.TransactionState<net.corda.core.contracts.ContractState>>) -> java.util.List<net.corda.core.contracts.TransactionState<net.corda.core.contracts.ContractState>> -> net.corda.core.contracts.TransactionState<net.corda.core.contracts.ContractState> -> data(net.corda.core.contracts.ContractState) -> state(com.luxoft.poc.mobi.data.state.TransportAgreement$State) -> Class class com.luxoft.poc.mobi.data.state.TransportAgreement$State is not on the whitelist or annotated with @CordaSerializable. java.io.NotSerializableException: net.corda.core.transactions.TransactionBuilder -> outputs(java.util.List<net.corda.core.contracts.TransactionState<net.corda.core.contracts.ContractState>>) -> java.util.List<net.corda.core.contracts.TransactionState<net.corda.core.contracts.ContractState>> -> net.corda.core.contracts.TransactionState<net.corda.core.contracts.ContractState> -> data(net.corda.core.contracts.ContractState) -> state(com.luxoft.poc.mobi.data.state.TransportAgreement$State) -> Class class com.luxoft.poc.mobi.data.state.TransportAgreement$State is not on the whitelist or annotated with @CordaSerializable.

What am I doing wrong? How do I work around it?

We use Corda 3.3

Based on the error message, you also need to add TransportAgreement.State to the whitelist, as you are sending it as part of the transaction builder.
