Network setup:
The network is setup with 1 orderer + 2 organizations with 2 peers each (2 * 2 = 4 peers).
I don't think there's a problem with the network, nor with the crypto materials, the channel config transactions, since I've done similar things using Fabric SDK Go without going into this kind of problem.
What I have done:
The error occurs after I created the channel "mychannel", added two peers of the client org to the channel, initialized the channel using Fabric SDK Java and then tried to update the channel.
Before I tried to invoke channel.updateChannelConfiguration() to apply the config tx file Org1MSPanchors.tx, I managed to get the signatures from the admins of both the orgs.
The key lines (the project is written in Kotlin, the following is the Java equivalent):
var updateConfig = new UpdateChannelConfiguration(new File("path/to/file.tx"));
// The signatures have been created from the admins of the 2 orgs.
channel.updateChannelConfiguration(updateConfig, signatures);
Logs:
After the invocation, the program crashed with the following info.

Please help:
If a solution is not obvious, could you please tell me what the possible causes are?
Thanks!
