ERROR R Source (Table) 3:1 Execute failed: Error in R code:
Error: target of assignment expands to non-language object
In the event you get this error message, just change the name of the file you are trying to read with readxl.
My scenario had files named 2020-ref… and by changing the name of the file to remove the hyphen and also move the numbers to the end of the file name, I was able to resolve the error.
If you search for this on other sites, the rabbit hole is endless. I compared the code to another workflow where I used the feature and found the only difference to be the file names. In all successful nodes the file names start with a string, non numeric character, and no -'s.
Hope this helps.
