Symptom
After upgrading to Exploratory Version 6.0.3, R Script Data Source that uses data.table::fread fails with error something like below.
i evaluates to a logical vector length 22 but there are 50 rows. Recycling of logical i is no longer allowed as it hides more bugs than is worth the rare convenience. Explicitly use rep(...,length=.N) if you really need to recycle.
Workaround
This might be fixed if you pass data.table=FALSE argument to data.table::fread
