Q&A
前提・実現したいこと
別途質問中のデバッグ中で不明な点が出てきたので、別立てで質問してます。
HTMLページをロード中、コンソールログに表題のエラー（下記に詳細）が出ます。この解消法を教えてください。
"/application-ac851418005bb337fe76.js.map"はpublic/packs/js/application-ac851418005bb337fe76.js.mapに存在してます。
またブラウザのコンソールからもソースマップエラーが出てます。このmapを探し出せていないようなので（404）なのです。

ウェブコンソールのエラー
ソースマップエラー: Error: request failed with status 404 リソース URL: http://localhost:3000/?debug=1&format=pdf ソースマップ URL: application-ac851418005bb337fe76.js.map
試したこと
Webpackerを利用している（Rails6のデフォルト）のですが、うまく取り扱えてません。
wicked_pdfのwicked_pdf-1.4.0/lib/wicked_pdf/wicked_pdf_helper/assets.rb中に後記のヘルパーメソッドが含まれていました。（抜粋）
なので、
<%= wicked_pdf_stylesheet_pack_tag "application" %> <%= wicked_pdf_javascript_pack_tag "application" %>
と
<%= stylesheet_pack_tag 'application' %> <%= javascript_pack_tag 'application' %>
は同値と思っていたのですが、
<%= stylesheet_pack_tag 'application' %>
だと件名のエラーがなく
<%= wicked_pdf_stylesheet_pack_tag "application" %>
だとエラーになります

public/packs/js/application-ac851418005bb337fe76.js.mapに存在してるのですと"/packs/js/application-ac851418005bb337fe76.js.map"ですね
