A strange error on the frontend blocking the functionality of the dashboard

Feature(s) impacted

Dashboard, smart actions.

Observed behavior

After entering the project from any account, an error occurs in the console.

message: "Ember Data Request GET https://api.forestadmin.com/api/users/82871 returned a 404\nPayload (application/json; charset=utf-8)\n[object Object]"

When I try to run smart action another error occurs


This is a production environment. There are no errors on the backend. No recent changes were made on our end. Only this error in the browser suddenly appeared.

Hi @Igor_Kovalenko,

Do you know exactly when it started to break?
Does it impact all your project users?

The first 404 error in your logs might not be problematic for the app.
Maybe we should focus on the Smart Action issue first, and dig into it to get more context.

Thanks for your help.

Hello @Igor_Kovalenko,

Thanks for the report.

What do you mean when you said that the functionality of your dashboard is blocked?
Do you have any screen / error message to share when in this situation?


Hello, @adriguy, @arnaud.

Do you know exactly when it started to break?
We received error report just few hours ago from our client.

Does it impact all your project users?
Yes, impact all project users.

Sorry for the misunderstanding. Unable to execute smart action.

Thanks for the insights.

It looks like the issue (“Can’t find api protocol” message) comes from the data API you host.
Are you sure you did not change some customization code (especially on your Smart Actions)?
Do these Smart Actions call other APIs in their controller implementation?

It seems you are right. There may be problems in the backend environment. I am currently investigating. Thanks for the help and sorry for the bother.
