bug: Issues with path-to-regexp after Bolt-JS upgrade to 3.21.4

[nivr4]

Hey,

Recently, we upgraded Bolt-JS in our Slack app to version 3.21.4. Since then, we've been encountering the following error:

/ticketing-system/node_modules/path-to-regexp/dist/index.js:136
        throw new TypeError(`Unexpected ${nextType} at ${index}, expected ${type}: ${DEBUG_URL}`);
              ^

TypeError: Unexpected ? at 36, expected END: https://git.new/pathToRegexpError

Do you have any suggestions for fixing this from our side, or should we downgrade to a previous version until the issue is resolved?

Thank you!

If you could help us reproduce the problem, that would be helpful to understand what is happening.

It seems the stack trace points to code that runs in the default error handler in the Socket Mode receiver.

Can you share your App configuration, and steps on how to reproduce? What event triggers this error? Do you have any handlers defined in your for the particular event?

Hi, I am working with Niv on this project. Currently we revert bolt version to 3.21.3 to avoid this errors. This is our app configuration:

const app = new App({
    token: config.SLACK_BOT_TOKEN,
    signingSecret: config.SLACK_SIGNING_SECRET,
    port: config.PORT,
    appToken: config.SLACK_APP_TOKEN,
    socketMode: true,
    customRoutes: customRoutes,
    logLevel: config.LOG_LEVEL,
    deferInitialization: true,
    logger: logger,
  });

@ShaiHalfon96 how can I reproduce the error? Please provide reproduction instructions. If I cannot reproduce the error, I cannot help 😢

Does it happen on app startup? Does it happen when a specific event occurs? etc.
