Hi, @artem_vysotsky - Sorry for the delay in your MR here: Don't fail when schema_at_breadcrumb does not have "properties" (!120) · Merge requests · Meltano / Meltano SDK for Singer Taps and Targets · GitLab I am not sure I follow the use case and I have posted a question for you there in the MR. Happy to also chat through it here in slack and/or in #C01QS0RV78D if helpful. Thanks!
