Intermittent error using R script in Power BI

I have a script that returns 2 years of closing prices for SPY.  Normally it runs without issue, but on occasion will resut in the following error: "Error in charToDate(x) :  character string is not in a standard unambiguous format"  Is there any way to trap records that cause the script to fail?  Here is the code:

 

if (!require(BatchGetSymbols)) install.packages('BatchGetSymbols')
if (!require(rio)) install.packages('rio')
library(BatchGetSymbols)
first.date = Sys.Date() - 1460
last.date = Sys.Date()
tickers <- c('SPY')
l.out <- BatchGetSymbols(tickers = tickers, 
                         first.date = first.date,
                         last.date = last.date, 
                         cache.folder = "C://users/owner/documents/r/BGS_Cache")


tickers<- as.data.frame(l.out)
library(rio)
write.table(tickers,file="Tickers.csv",sep=",")

Thanks for all advice.

 

Regards

Hi @JimB-GA

Have you changed some date values ever since?

 

I'm not the expert of R, i searched but don't find any known issue regarding R script in Power BI like this problem.

 

As searched, there are some links you may look into.

What are the “standard unambiguous date” formats?

I have been using BatchGetSymbols successfully (most of the time).  There is some record in the return dataset that has a bad date format in it that I can't find.  Looking to find a way to ensure all dates are in an unambiguous format.
