custom R visual runtime error (access denied to local url)

[chriswalz]

Hi,

I have created a custom Power BI visual using this http://radacad.com/interactive-map-using-r-and-power-bi-create-custom-visual-part-1 tutorial. I'm using Plotly to create a interactive chart in this visual.

I can use this custom visual without any problems in power BI desktop, but when I publish it to powerbi.com, I receive the following error "script runtime error":

Error in shell.exec(url) : access to 'C:\Users\Client\Temp\RtmpOsE2VBviewhtml1c717b3ce9/index.html' denied

Does anybody have an idea what's causing this error?

The following R code has been used to create the visual:

source('./r_files/flatten_HTML.r')

Hi chriswalz,

I am having the same problem and the suggestion marked as the solution below does not work for me.

Did you have your problem fixed?

Hi @chriswalz,

In your statement, you use source('./r_files/flatten_HTML.r') to cite other R statement, please use the detailed R in the .r file statement to replace the "source('./r_files/flatten_HTML.r')", and check if it works fine. And please follow this blog to check if there is unsupported packages in your .r file.

Best Regards,
Angelia

Hi @v-huizhn-msft,

thanks for your response - unfortunately they didn't solve this issue. Still getting the access denied runtime error. I also checked the packages but all packages i'm using are on the list of supported packages.

Best regards,

Chris

I've received the solution from Microsoft support that worked for me.

Simply remove the plot_ly conversion in the end:

(gg <- ggplotly(g))

and use 'g' as input for internalsavewidget because 'g' is already a plot_ly object.

Not sure why this leads to an error in PowerBI service because converting a plot_ly object to a plot_ly object shouldn't be a issue.
