Error when running Recalc from CMDT

[Dustin-Northcutt]

I'm getting this error when doing a rollup of LAST activityDate on Task to Account. When I run the rollup on a single record by temporarily adding an accountId filter in the where clause it works fine, but recalculating the entire population of accounts causes the error. Rollup custom metadata is attached. Thanks in advance for any help/guidance!

Failed to process Queueable job for class RollupFullBatchRecalculator for job ID 707Pk00001wF0z9.

That's ... a fascinating Data Weave error! I will have to take a look at this and see if I can put a work-around in place.

@Dustin-Northcutt I was able to start diving into this issue today and I've found that it happens with any Date / Datetime values. I have a fix for Dates but wasn't able to fully fix Datetimes before stepping away for the day. I will continue working on this and will try to get a fix for this in the upcoming release
