Cedar not working - TypeError: keys.reduce is not a function

[fionajrenton]

My code using cedar charts no longer works and even your documentation pages such as this one:
https://esri.github.io/cedar/
have the same error:
Uncaught TypeError: keys.reduce is not a function
at Object.appendCustomParams (append-custom-params.ts:32)
at Object.queryFeatures (query.ts:173)
at query.js:23
at Array.forEach ()
at queryDatasets (query.js:8)
at Chart.query (Chart.js:92)
at Chart.show (Chart.js:116)
at displayChart ((index):193)

This worked fine two weeks ago. I was out last week.

thanks for reporting this.

the documentation page is currently loading a version of @esri/arcgis-rest-request that is too new.

we will have the problem fixed shortly. sorry for the inconvenience!

The docs are fixed: https://esri.github.io/cedar/

@fionajrenton until we cut a new release, you may need to do as @jgravois suggests and ensure that your app is using version 1.x of the arcgis-rest-js packages.
