I encountered an issue when using a term serializer and a custom content type. Failing test is included (if fix is not applied). With the JSON 'hack' mentioned in the code I'm not sure if this is the right fix, but it works for me :)

@dvic many thanks for this, the solution proposed is great. I've just added some comments then we are ready to merge.

👍 done, I've made the struct check also more specific, it should check specifically for %SnapshotData{} right?

LGTM

@dvic I will wait a few days before the release to see if there is something else I need to include

@dvic I've just released v0.1.2 on hex, which includes your patch.
Note that one test is still failing, since this adapter does not support partitioning. The tests are inherited from commanded dep and there is no way to skip them.
