R Snippet Error on Mac

Hi! This is my fist time writing on the forum and i’m quite new to Knime.

I’m having some issues with some R Nodes, some work fine and some give me this error:

"Execute failed: R evaluation failed.: “knime.tmp.ret<-NULL;printError<-function(e)

message(paste(‘Error:’,conditionMessage(e)));for(exp in tryCatch(parse(text=knime.tmp.script),error=printError)){tryCatch(knime.tmp.ret<-withVisible(eval(exp)),error=printError)

if(!is.null(knime.tmp.ret)) {if(knime.tmp.ret$visible) tryCatch(print(knime.tmp.ret$value),error=printError)}};rm(knime.tmp.script,exp,printError);knime.tmp.ret$value”

when i evaluate the script within the node i get no errors, however i’m not able to execute the node.

I think the problem is Mac related, since i tried to run the workflow on a Windows and it works. I read multiple entires in the forum with similar problems and tried to fix it by updating RServe, downloading all the suggested support programs like Xcode, Xquarz, Fortran, … but nothing seems to solve the problem.

My MacOS is Big Sur 11.2.3

Knime 4.5.1

R 4.1.2

RServe 1.8-10

Thank you
