Sourcemaps not working status code 404

[dschulten]

I have enabled sourcemaps by adding prettySourceMap (slightly convoluted, using the xray plugin for uploading reports to Xray):

export default defineConfig({
  e2e: {
    specPattern: "**/*.feature",
    async setupNodeEvents(
      on: Cypress.PluginEvents,
      config: Cypress.PluginConfigOptions
    ): Promise<Cypress.PluginConfigOptions> {
      const fixedOn = fix(on);
      await addCucumberPreprocessorPlugin(fixedOn, config);
      await configureXrayPlugin(fixedOn, config, {
        jira: {
          projectKey: "KMPS",
          url: "https://jira.example.com",
        },
        cucumber: {
          featureFileExtension: ".feature"
        },
        http: {
          httpsAgent: new Agent({
            secureOptions: constants.SSL_OP_LEGACY_SERVER_CONNECT,
          }),
        },
      });
      fixedOn("file:preprocessor", async (file: Cypress.FileObject) => {
        syncFeatureFile(file);
        const cucumberPlugin = createBundler({
          plugins: [createEsbuildPlugin(config, { prettySourceMap: true })],
        });
        return cucumberPlugin(file);
      });
      return config;
    },
  },
  video: false,
});

The Cypress Electron debugger now shows my feature file and step definitions as nodes in the left-hand-side tree below Your Spec, but in the source window on the right it says:

Could not load content for http://localhost:3000/__cypress/cypress\e2e\1_KMPS-2_KMPS-34_KMPS-116.feature (HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE)

I am obviously on a Windows machine. The project is a Next.js application.

I tried to fix the url, replacing the backslashes by slashes, and tried to GET it with a Restclient but that did not help - I get a Next.js 404 response.

Sourcemaps for debugging with esbuild must be enabled using sourcemap: 'inline' as shown below. The option prettySourceMap is for a different purpose.

on(
    "file:preprocessor",
    createBundler({
      sourcemap: 'inline',
      plugins: [createEsbuildPlugin(config)],
    }),
  );
