Confirmed. This is an issue, solution below.
Root Cause, the images were versioned with vX.Y.Z, but then starting with 1.2.4, they are not versioned as X.Y.Z.
Unfortunately, this is not consistent, and the chart, when the chart was updated, I should have tested this fully. I didn’t really the version scheme was changed. Grr.
Workaround:
helm install \
my-dgraph-lambda \
dgraph/dgraph-lambda \
--set image.tag=1.2.4
