Hi @Paul_Danyliuk I’m having the same problem with a Notify formula that used to work, but is now giving this error message: "coda notify expects parameter to be a row, list of rows, or a column, but found CurrentValue, which can match a current value, or a text value" 
I tried to add your recommended fix above but am still getting the same error, so not sure I did it quite right?
This is the part of my original formula which is throwing the error:
RunActions([Company Request List].Filter([Project Name]=thisRow and Select=true AND [Contact Request Sent]=false and [Sales Owners Email].IsNotBlank()).[Sales Owner].Unique().FormulaMap(Notify(CurrentValue, Concatenate("Hi ", CurrentValue.Name.Split(" ").First(),", ",thisRow.Requestor," has requested to contact your customers for the project \"", thisRow.[Project Name], "\".", " Please follow this link to review: ", "https://coda.io/d/Research-Recruitment-Sales-Contact-Requests_dPIVcb_2VGa/Your-Contact-Requests-to-Review_subwF#_lu82m"))),
and this is how I tried to fix it using your suggestion above:
RunActions([Company Request List].Filter([Project Name]=thisRow and Select=true AND [Contact Request Sent]=false and [Sales Owners Email].IsNotBlank()).[Sales Owner].Unique().FormulaMap(Notify(CurrentValue, Concatenate("Hi ", CurrentValue.Name.Split(" ").First(),", ",thisRow.Requestor," has requested to contact your customers for the project \"", thisRow.[Project Name], "\".", " Please follow this link to review: ", "https://coda.io/d/Research-Recruitment-Sales-Contact-Requests_dPIVcb_2VGa/Your-Contact-Requests-to-Review_subwF#_lu82m"))),
would very much appreciate any suggestions you’re able to give as to how I might be able to get this working again!
Thanks in advance,
Elley
