stucco / document-service Goto Github PK

On my vagrant environment , the doc-service have this error :

Unable to create the metadata database data/doc.db: invalid argument.

and I trace back to the code and I found that this error was risen here:
database, err := bolt.Open(f, 0600, &bolt.Options{Timeout: 1 * time.Second}) if err != nil { log.Fatalf("Unable to create the metadata database %s: %s", f, err) }
which in the doc-service.go 153 line.

I tried some solutions , such as change the dataDir into empty and in anohter file , but it still make this error.
I wonder where is the problem.
Thanks a lot.
