Unknown column 'lazy' in 'field list' when upgrading from 28.0.1.1 to 29.0.3.4

[j-ed]

Due to the fact that a missing index has been addressed last week in the following ticket, I assume that the field is still required:

[Bug]: Missing index for oc_appconfig.lazy

Have you tried to add the missing field manually to get rid of the error message?
Nevertheless it might be worth to open an issue ticket in the Github repository to get it fixed in the docker image:
