If you want to include a polyfill, you need to:          - add a fallback 'resolve.fallback: { "assert": require.resolve("assert/") }'          - install 'assert'  If you don't want to include a polyfill, you can use an empty module like this:          resolve.fallback: { "assert": false }   @ ./node_modules/knex/lib/knex-builder/Knex.js 2:21-53   @ ./node_modules/knex/lib/index.js 1:13-43   @ ./node_modules/knex/knex.js 8:13-35   @ ./src/main-vanilla.js 34:11-26    ERROR in ./node_modules/pg-connection-string/index.js 4:9-22  Module not found: Error: Can't resolve 'fs' in '/var/www/html/xxx/node_modules/pg-connection-string'   @ ./node_modules/knex/lib/knex-builder/internal/parse-connection.js 1:18-49   @ ./node_modules/knex/lib/knex-builder/internal/config-resolver.js 4:24-53   @ ./node_modules/knex/lib/knex-builder/Knex.js 7:26-63   @ ./node_modules/knex/lib/index.js 1:13-43   @ ./node_modules/knex/knex.js 8:13-35   @ ./src/main-vanilla.js 34:11-26    ERROR in ./node_modules/tarn/dist/Pool.js 7:17-34  Module not found: Error: Can't resolve 'timers' in '/var/www/html/xxx/node_modules/tarn/dist'    BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.  This is no longer the case. Verify if you need this module and configure a polyfill for it.    If you want to include a polyfill, you need to:          - add a fallback 'resolve.fallback: { "timers": require.resolve("timers-browserify") }'          - install 'timers-browserify'  If you don't want to include a polyfill, you can use an empty module like this:          resolve.fallback: { "timers": false }   @ ./node_modules/tarn/dist/tarn.js 3:15-32   @ ./node_modules/knex/lib/client.js 1:31-46   @ ./node_modules/knex/lib/knex-builder/Knex.js 1:15-35   @ ./node_modules/knex/lib/index.js 1:13-43   @ ./node_modules/knex/knex.js 8:13-35   @ ./src/main-vanilla.js 34:11-26    24 errors have detailed information that is not shown.  Use 'stats.errorDetails: true' resp. '--stats-error-details' to show it.    webpack 5.21.2 compiled with 24 errors and 2 warnings in 8772 ms  ℹ ｢wdm｣: Failed to compile.  

Any ideas how to resolve this? Do we need to install every 'missing stuff' like timers-browserify?
