NoSuchMethod error on debezium-source startup

[sixpounder]

Using debezium-source 5.0.0 (or 5.0.1, as far as I can tell) and configuring it for a mongo source I experience the following error at start time:

Debezium Engine completed with success:false, message:null 
Exception in thread "debeziumPublisher.debezium:inbound-channel-adapter#0-thread-1" java.lang.NoSuchMethodError: 'com.mongodb.connection.SocketSettings$Builder com.mongodb.connection.SocketSettings$Builder.connectTimeout(int, java.util.concurrent.TimeUnit)'

I did a little investigation and from what I can put together this image uses debezium core 2.6. Looking at its code it seems to expect, at least at build time, the version of mongo-driver-core (which contains the definition of the method connectTimeout) to be 4.11, which indeed defines the method so that it takes two arguments, one int and one TimeUnit.

However, at runtime it looks like the image uses a version of mongo-driver-core that is 5.0.1, and that version contains a definition of that method that accepts a long as first parameter, and would therefore justify the error we are seeing.

Is it possible that somewhere in the build process these dependencies are mis-versioned?

I can provide further details if needed

Thank you in advance

I've just ran dependencies for the spring-debezium-supplier which is a core for this debezium-source:

+--- io.debezium:debezium-connector-mongodb -> 2.6.2.Final
|    +--- io.debezium:debezium-core:2.6.2.Final (*)
|    \--- org.mongodb:mongodb-driver-sync:4.11.0 -> 4.11.5
|         +--- org.mongodb:bson:4.11.5
|         \--- org.mongodb:mongodb-driver-core:4.11.5
|              +--- org.mongodb:bson:4.11.5
|              \--- org.mongodb:bson-record-codec:4.11.5
|                   \--- org.mongodb:bson:4.11.5

Not clear how that MongoDB driver 5.0.1 gas slipped into runtime...

[sixpounder]

Ok, after a day of staring at my configs this feels reassuring 😊

[sixpounder]

I should clarify that this is happening using the docker version of the application

[artembilan]

Yes, I saw that note from your original post.
Can you point to that image, please?
Did you try your solution with latest version, which is 5.1.0?

[sixpounder]

Yes I did, I also tried the latest snapshot to the same effect.

The thing that stands out for me is that this problem start with the image at version 5.0.1, that has mongo driver at version 5.0.1. It's almost like that versioning "automatically" bumped the mongo driver version as well.
