@SpencerKaiser Thanks for the report. Unfortunately this library has not seen much use by our customers so we're not able to spend significant resources maintaining it. However it is an open source project and we welcome a fix from the community for this issue.
Note that the node.js library is using currently performing image generation using a legacy endpoint (
/apigenimage). Switching to the new endpoint, available and documented here, is likely to fix this issue as well as #55. The new endpoint takes the same JSON body but authentication has changed somewhat.SpencerKaiser commentedon Apr 12, 2018
@scjody thanks for the update. I used Plot.ly as part of my company's CI/CD solution along with Artillery.io to generate performance test graphs for some of our new services. If we scale things up and get a license, I may try to update the SDK for that new endpoint!
