Errors occur during runtime when `bootstrap/cache` has `routes.php` or misses `packages.php` and `services.php`

[pjxiao]

The problem

• a. When I deplyed my codes where boostrap/cache directory has routes.php (along with packages.php and services.php), the deployed lambda function failed because the route cache has an invalid format.
• b. When I deplyed my codes where boostrap/cache directory has packages.php and services.php, the deployed lambda function failed because the cache directory is absent or isn't present.

Questions

• a. Should I exlude routes.php from a deployment package?
• b1. Should I include packages.php and services.php?
• b2. Is it safe to deploy locally generated packages.php and services.php to Lambda? (In other words, do those caches not depned on an environment where they were generated?)

An environment

• php: bref:layer.php-73
• Laravel: 6.20.7
• laravel-bridge: 1.0.0

Did you ever find a solution ?

What I don't understand with this issue is how does that situation happen?

When following the official documentation is there any problem?

Sorry, I've left the team where bref was used, and I've forgotten the problem details. They may have used an older version. So I'll close this issue. I appreciate your replies.
