We are getting the following error while saving a Data-Transform rule into the Branch in 8.2.2 version Source— Invalid expression or reference: error: both the name and value must be provided for parameters to the data page : However it saves properly in 7.4 version. Any quick suggestion would be appreciated. Thanks Nagi System Administration Upgrades × Close popover Facebook Twitter Linkedin Email Copy Link Copied!
