Problem running an R Script to read a JSON file and create a dataframe in power BI

[Art]

I am gettting the below error while running my R script in power BI . The script runs fine in R studio. In the options in power BI I have specified the right path for R-3.5.0

unable to connect

we encountered an error while trying to connect

Details: "ADO.NET: R script error.
Error: lexical error: invalid char in json text.
output10.json
(right here) ------^
Execution halted
"

The first few line of code are below 

library(jsonlite)
library(plyr)

P<-fromJSON("output10.json")
summary(P)

Anybody know why ?
