Hello guys, I’m trying to implement elasticsearch in my node.js backend but I am seeing this error. I am unsure where this is originating, and I believe it is specific to Liana.

My package.json

"forest-express-mongoose": "^9.2.0",
"forest-express-sequelize": "^9.2.6",
"@elastic/elasticsearch": "^8.6.0",

“express”: “~4.17.1”,

Please assist.

Hello @tanish,

Can you explain in which circonstances the error occurs? Is it when the server is launched? When it receives a specific request?

Is it a new project? Can you please share with us the name of the project?

Can you also explain what you changed? Did it work before your changes?

I am currently using mongodb for my primary db.

But as I said, I’m trying to use elasticsearch for read only purposes.

In my routes folder, I created a file and added this code. It seems this line

const {
} = require(‘forest-express-sequelize’)

causes the issue.


Are you accessing any SQL databases?

I am not. I am trying to access an elasticsearch database to improve read performance. I have set up a client. According to the documentations, the queries use sql right? or am I incorrect about that?

Ok, thanks.

Then you don’t need the dependency forest-express-sequelize which is meant to be used with SQL databases.

In your case, you need to add a smart collection to your project declared with forest-express-mongoose

We have a documentation here with an example: Another example - Woodshop

In your case, you have to replace references to forest-express-sequelize by references to forest-express-mongoose.
