When using the current release of the arcgis-js-api (4.20.2) and using the local assets (esriConfig.assetsPath = "./assets"😉 the assets do not seem to be up to date, i receive the following message on load:
30cfa4b0-c6b0-4fa5-a5e1-ac799d7f3ee0:1 [esri.core.workers] Version mismatch detected between ArcGIS API for JavaScript and assets:
API version: 4.20 [Date: 20210707, Revision: 17f9314e]
Assets version: 4.20 [Date: 20210701, Revision: d19b8a11]
This appears to manifest in a missing file:
message: "Uncaught NetworkError: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'assets/esri/core/workers/chunks/4ec871ce4f503ff84927.js' failed to load."
