resolves #3603

I assert that the build errors are unrelated to my changes, as the same thing is happening in other PRs, and it comes from a code path that I did not touch.

PR are now passing in the pipeline. I will do another try for the build. I will recommend that you get latest from v4.x into your branch if it is not working.

[mattchenderson]
