What is the expected behaviour?

it imports the dump

How can the behaviour be reproduced?

I can share a link with my dump.

@awb99 I had this issue the other day in prod. Basically in v0.4 the datoms were backed up as simple edn. The new version expects a binary data type as that is what it emits. Not ideal.

Seems to have been introduce in [#496]. @yflim any possibility of making import backwards compatible?
