Issue updating state on re-deployed Corda Enterprise App

Question

I have encountered an issue when re-deploying a Corda Enterprise app after changing some ledger code and trying to update a state created by the old deployment. Initially I encountered a Notary issue caused by the following TransactionBuilder constraint:

    require(notary == this.notary) { "Input state requires notary \"$notary\" which does not match the transaction notary \"${this.notary}\"."

This was solved by using the NotaryChangeFlow. An example of my usage is below:

        val inputNotary = inputState.state.notary
        if(inputNotary != newNotary) {
            subFlow(NotaryChangeFlow(inputState, newNotary))
        }

However, I am now getting the error:

java.lang.IllegalArgumentException: Don't know about O=Party, L=Sydney, C=AU

I was wondering if anyone has seen this error before / knows what could be causing it. It seems related to the transaction referencing the original O=Party, L=Sydney, C=AU Party which was a participant in the initial state creation. This Flow worked fine in Corda OS but is causing problems after migrating to Enterprise.

Answer 1

You say in your comment above:

Just confirming the ./gradlew deployNodes command is the correct one to re-deploy nodes after changes are made

This is incorrect. Re-running deployNodes will create a new set of nodes with a new set of certificates. This is why you're getting exceptions of the form java.lang.IllegalArgumentException: Don't know about O=Party, L=Sydney, C=AU.

You should update the CorDapp using the following process instead:

• Put the node in flow-drain mode, as per the instructions here
• Once flow-drain is complete, turn off the node
• Build the new CorDapp JAR by following the instructions here
• Install the new CorDapp JAR by following the instructions here
• Restart the node
