@nvkelso I would like to point out that some recent changes introduced more integration tests failures. Attention that the linters check is important, if the linter tests failed it won't run the integration tests and may hide the problems. One we way can do is to change the settings of the repo so that each merge have to rebase master before merging. Also to have a clearer view on which commit breaks things, we might want to try squash and merge instead of merge request, otherwise the history of commit on master are interleaved with older commits from a PR once it was merged.

If we scan the master branch and use this commit as baseline https://github.com/tilezen/vector-datasource/commit/cab179d141667919f54735a7d1e6513e69b0f9c4 it had 8 integration tests failures

then this commit https://github.com/tilezen/vector-datasource/commit/5dfc1d1d697a648f846646a4a20596b2b98b19e6 increased it to 90

then this commit https://github.com/tilezen/vector-datasource/commit/d8b7dbe822e4d37578443f235f59a8ef89e3c136 might be the one that increased it to 91 (cc @iandees )

and now at the time of writing the number is 92 according to https://github.com/tilezen/vector-datasource/pull/2036 it might be introduced by https://github.com/tilezen/vector-datasource/pull/2015
