Error in PLP when called from Strategus

[TomWhite-MedStar]

When running either of the two main Strategus projects (AntiVegf and Flouroquinolone), the run fails during PLP with this message:
Error in !migrations$executed : invalid argument type
This occurs at line # 216 of DataMigrationManager.R
The line in question is migrations[!migrations$executed, ]

I am using R version 4.2.3
I happen to be using Databricks, but the error appears independent of the DBMS.

The root issue may be line 130 in DataMigrationManger.R, which returns and empty data.frame(). So if migrations <- data.frame(), then migrations$executed is NULL and !migrations$executed throws invalid argument type
