Unable to insert document with a field of type BsonBinary

[mcveighc]

When trying to create a collection and seed some data as part of a changeUnit i receive the following error because my model has a field of type BsonBinary.

Caused by: org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for class org.bson.BsonBinary_$$_mongock_78c_5.

This is a valid type as its used as part of the Client Side Field Level Encryption. Is the mongo-driver used by mongock out of date with the latest version used in spring boot? Are there any workaround for this?

Hello @mcveighc ,

the MongoDB driver dependency is imported by your project, if you see the scope is provided, so that shouldn't be the problem.

Have you tried that without Mongock, I believe is not related to Mongock nor MongoDB driver. Instead I think somehow the codec is missing and needs to be provided

@dieppa thanks for quick response.

Yeah strangely it works fine when i use my mongo repository with the same model. I tried a few different routes to insert the data in the changeUnit and seemed to get the same or similar issues.

• Inject mongoTemplate via method parameter
• Inject mongoTemplate via constructor parameter
• Inject dedicated repository via constructor parameter and insert
• Grab the collection from the mongoTemplate using codecs from MongoClientSettings.getDefaultCodecs() and insert

It almost seems when running in the mongock boundary it cant find them for some reason.

Hello @mcveighc ,

I think the easiest way to approach this is you setting up a dummy project in github reproducing this issue, grant me access and I can debug it. Is that something you can do?

Hi @dieppa

I've created a private repo and added you as a collaborator. There are instructions on the readme how to run it.

Let me know if you have trouble. Thanks
