Firebase - Issue during deployment getting error : Error: An unexpected error has occurred - node.js

Question

When i test my application using the below command in the localhost, it works fine.
firebase serve --only functions,hosting
But when i tried to deploy it using below command. It fails with error message (Error: An unexpected error has occurred.). Does not give much details
firebase deploy
or
firebase deploy --only functions,hosting
Initial error was to update firebase-functions and firebase-admin so i went ahead and updated it after reading the guide in below link. Iam not using any of those features.
https://firebase.google.com/docs/functions/beta-v1-diff#realtime-database
npm install firebase-functions#latest --save
npm install firebase-admin#5.11.0 --save
npm install -g firebase-tools
Here is the output using command : firebase deploy --debug

[error] Error: An unexpected error has occurred.
And my firebase.json file looks like this
{
"hosting": {
"public": ["public/", "public/css", "public/js", "public/mdb-css", "public/mdb-js", "functions/js", "public/images"],
"rewrites":[
{"source" : "/timestamp", "function" : "app"},
{"source" : "/stashlogin", "function" : "app"},
{"source" : "/stash", "function" : "app"},
{"source" : "/get", "function" : "app"},
{"source" : "/put", "function" : "app"},
{"source" : "/categorycolor", "function" : "app"},
{"source" : "/category", "function" : "app"},
{"source" : "/category/**", "function" : "app"},
{"source" : "/put/**", "function" : "app"},
{"source" : "/delete/**", "function" : "app"},
{"source" : "/profile", "function" : "app"},
{"source" : "/feedback", "function" : "app"}
],
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
]
}
}
Please let me know how to proceed as there is not reason for the error message. I am actually stuck.

Answer 1

Your public directory must be a single string, not an array.
