    Bootstrap 5.3.0 (latest at the moment) added support for dark and light modes.

    I have solved the same problem (although unrelated to ReactJS) by adding new bootstrap source file variables-dark.scss, after already existing variables.scss in my main site.scss file:

    // site.scss
@import "../node_modules/bootstrap/scss/variables";
@import "../node_modules/bootstrap/scss/variables-dark";

    More details can be found in Bootstrap Sass documentation for version 5.3 here.

    Other, perhaps easier option, if your ReactJS framework does not support Bootstrap 5.3 yet is to lock version of Bootstrap in package.json file to 5.2.x for now:

    "dependencies": {
  ...
  "bootstrap": "^5.2.0"
  ...
},

    I think you need to specify Bootstrap version as 5.2.x, not above. Bootstrap 5.3 requires the import of scss/variables-dark
