R package compatibility bug in the Power BI Service between dplyr and rlang versions.
rlang package appears to have been updated to version 0.3.0 (despite the documentation still citing 0.2.0).
This version is incompatible with the version of dplyr the documentation suggests is loaded for the Power BI Service (says 0.7.4).
dplyr needs to be updated to 0.7.8 else will error out scripts and is making the filter() function unusable. This is a key operation of dplyr after all...
This error was logged as a version bug in the dplyr github repo back in OCtober 2018.
Key production reporting is currently affected and this should be an easy fix on MSFT part, not expecting users to rescript their report visuals.
Please address and respond as I will need to feed back to stakeholders as to why their reports have huge errors in them. Note thiese visuals work perfectly in PBI Desktop...
