Unable to export graph to pdf (Error 402 received)


I’m using the latest drop of plotly from github, this appears to fix the issue related to the HTTP 500 error. And while i can export a png successful via command line I get an error trying to export as pdf:

If I run

plotly_IMAGE(field.defects.df.weekly.pc.bar, width = 1000, height = 400, format = “pdf”, scale = 2,
out_file = “~/Desktop/Graph6.pdf”)

I get:

Error in process.image(append_class(resp, “image”)) : Payment Required (HTTP 402).

Please advise
