webasset not showing updated files

Question

I have a question about webasset.

I am using ckan. I updated a library in ckanext_geoview plugin in ckan. But when calling this library with webassets comes the old version. What path can I follow?

webassets.yml like this

openlayers_js:
  filter: rjsmin
  output: ckanext-geoview/%(version)s_openlayers.js
  extra:
    preload:
      - base/main
  contents:
    - js/vendor/underscore/underscore.js
    - js/vendor/proj4/dist/proj4-src.js
    - js/vendor/openlayers/ol-debug.js
    - js/vendor/ol-helpers/ol-helpers.js
    - js/vendor/ol-helpers/ol-layer-switcher.js
    - js/ol_preview.js

updated the underscore library to version 1.13.4

but old version is coming

What should I do to make the existing javascript files appear? I would be glad if you could help me.
