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."

Thanks Andy,

I don't usually need to do this but we have a client in a sandboxed environment.

I have resolved the issue by using a grunt task to touch the asset files

 grunt.loadNpmTasks('grunt-touch');
  grunt.initConfig({
    touch: {
      options: {
        match: true,
        mtime: true
      target: ['pathto/assets/**/*'],
grunt.registerTask(['touch']);

I feel this issue might be related to the RemoteClient.js, when I look at this file in windows it has an incorrect date

Update: https://github.com/npm/npm/issues/20439 looks like this is caused by an npm "feature", any copy that uses the last modified date is having issues (dojo copy?, aws s3 sync?)
