Anyone has any ideas how to solve this error?

Error reading file 'infra/package.json' when computing package dependencies. Error: ENOENT: no such file or directory, open '/infra/package.json'

My dir:

- project
    ...
    - infra
        - Pulumi.yaml
        - tsconfig.json
        ...
    - src
       ...
   - package.json
   - tsconfig.json

I need to have the package.json at that place in my directory. Any help or alternatives to solve the problem will be welcome. I'm using

@pulumi/pulumi: "^3.4.0"

this error occurs when i run

pulumi preview --cwd infra

I run that command in the root of my project
