Because the code relies on the backend, you have to set the backend _before_ you can run the code. You can't set it in the code without using something like Automation API (in which case you'd set up the stack, including the backend, and execute the various stack operations like preview, up, destroy, etc. from the Automation API code).

yes i'm using automation api but how to set this backend login ?

Have a look here: <https://www.pulumi.com/docs/concepts/state/>

I haven't tested/tried this, but it looks like specifying it using the `PULUMI_BACKEND_URL` environment variable or putting it in the stack configuration might work for you.

Example
```PULUMI_BACKEND_URL="s3://<bucket>/<path>/?region=us-east-1&awssdk=v2"```
