Cross Drill from UX failed when element name has []

Hi there,

We are trying to right click an element on a Grid widget, and wanted to do a cross drill, but for some reason, it does not work, it is throwing CommitRollback error, is this a defect of UX or defect of TM1?



some screenshots for additional information

error in console after clicking “Drill down by…” but no response

message log from TM1 instance

message log from content store instance

After more detail analysis, it appears to be caused by element name with [] brackets, so it’s very likely to be a defect of UX.
