Is there a way to translate an attribute id to the corresponding ident?

Wed, 11 Nov 2020 15:09:13 +0000

I could not find how to do it serching the documentation, if you could point out where, it'd be appreciated.

Example: with the following data (excerpted from an ExceptionInfo):
{:data [:db/add -9223301668109517911 112 nil], :db/error :db.error/nil-value, ...}
What we'd like to know is which :db/ident has the id 112.
Is there a way to do it?
