Description
Hello maintainers!
I am working with Chart.js and Chartjs-adapter-moment to display a historical trend of up to 19 datasets using Flask. I am running into the issue where the adapter is returning the below error:
Uncaught TypeError: Cannot read property '_adapters' of undefined
at chartjs-adapter-moment.min.js:formatted:29
at chartjs-adapter-moment.min.js:formatted:8
at chartjs-adapter-moment.min.js:formatted:9
As well as this additional chart.js error:
Uncaught TypeError: Cannot read property 'left' of undefined
at _isPointInArea (chart.js:1339)
at getNearestItems (chart.js:1775)
at nearest (chart.js:1858)
at Chart.getElementsAtEventForMode (chart.js:6857)
at Chart._handleEvent (chart.js:7091)
at Chart._eventHandler (chart.js:7074)
at listener (chart.js:6971)
at Chart.event (chart.js:2431)
at chart.js:34
Versions:
Chart.js 3.2.0
Moment.js 2.29.1
Chartjs-adapter-momentjs 1.0.0
The time format is ISO 8601, and I had the implementation working on Chart.js version 2.6.0 but I needed to upgrade to get the zoom plugin to work. And now the chart will not build with the two above errors.

Research direction
Reproduce the failure with Chart.js 3.2.0, Moment.js 2.29.1, and chartjs-adapter-momentjs 1.0.0, using the ISO 8601 time format and the historical multi-dataset chart described here. Start with the stack traces in chartjs-adapter-moment.min.js and chart.js; done means the chart builds without either reported TypeError.
