Hello API Scripters! From the Pro Thread : We've got some new API server updates ready for testing on the dev server! These changes are intended to improve the stability of our API servers and to help us get more information about their performance. This update will not immediately improve API slowdown issues that are being reported but it will allow us hone in on a root cause. For API scripters: we've updated node to the most recent stable release, supporting features from ES2018/2019+ and more. Lastly, anticipate that this update will resolve a large number of issues relating to sheetworkers not being triggered by the API. We appreciate your help in testing out these changes in order to help us get them to live as quickly as possible. You can test out the changes on the dev server, and discussion is happening on the pro thread here .
