Gin gives "pattern matches no files" error

Help

How can I deploy my project to serverless functions without “unable to match html templates” error?

I have my code setup so it finds external html file templates in the “external/html” directory using the LoadHtmlGlob function gin provides.

Instead of loading and serving the html content, it instead errors saying that the pattern provided can’t find any files.

// api/index.go
func Handler(w http.ResponseWriter, req *http.Request) {
  gin.SetMode(gin.ReleaseMode)
  r := gin.Default()
 
  r.Use(Cors())
  r.LoadHtmlGlob("/external/html/*.html")
  //***
}

//vercel.json
{
    "version": 2,
    "routes": [
      {
        "src": "/(.*)",
        "dest": "/api/index.go"
      }
    ]
  }

Project structure:
.
├── api
│ └── index.go
├── external
│ ├── html
│ ├── models
│ └── util
│ ├── bucket.go
│ ├── database.go
│ └── redis.go
├── .env.local
├── .env.prod
├── .gitignore
├── go.mod
└── go.sum

Hi @butterfriez, welcome to the Vercel Community!

Have you tried using the includeFiles option from the Function | Project Configuration in your vercel.json?

I think including the file in your function code should resolve the issue.

I’d also recommend removing the legacy routes option and use the rewrites option instead.
