Objection.js: mapping.relation is not a function
Getting a bunch of mapping.relation is not a function after project dependencies update (long time, 6+ months), is there perhaps a quick reason / suggested fix? Anyone encountered this? The models in my project are based on the ES7 documentation.

Are you using the old OneToOneRelation and OneToManyRelation types? They were deprecated and eventually removed. You should replace OneToOneRelation by BelongsToOneRelation and OneToManyRelation by HasManyRelation.

Yes, I think that's it! Thank you for the super quick response

Just for others, I ran into this issue when I made a typo. I wrote Model.ManyToManyRElation. So this occurs (presumably; haven't glanced at the source) if you forget to define the relation field of a relation! Could probably do with an actual error message... Odd how specifying a function specifying a complex validation doesn't validate its arguments! :stuck_out_tongue:
