[guoxiangke]

Hello, I deploy a laravel to vercel, the homepage works well.
But after I config cache drive, there are something wrong, I want debug. while the logs show like this.
which transcated, no No1 line.

• Version: vercel-php@0.5.2
• URL: No

BTW, the laravel works well with predis cache from upstash on my local.
Also the LOG_LEVEL and debug set true, but always show 500.
