can you share your `package.json` and the output of `pulumi plugin ls`

plugins:

```NAME            KIND      VERSION  SIZE    INSTALLED  LAST USED
aws             resource  5.3.0    368 MB  n/a        1 day ago
aws             resource  5.2.0    368 MB  n/a        3 days ago
aws             resource  4.38.1   350 MB  n/a        2 hours ago
aws-apigateway  resource  0.0.6    171 MB  n/a        2 hours ago
docker          resource  3.2.0    40 MB   n/a        1 day ago

TOTAL plugin cache size: 1.3 GB```

Package.json:

```{
    "name": "store_event",
    "devDependencies": {
        "@types/node": "^14"
    },
    "dependencies": {
        "@pulumi/aws": "^5.0.0",
        "@pulumi/aws-apigateway": "0.0.6",
        "@pulumi/awsx": "^0.40.0",
        "@pulumi/cloud": "^0.30.1",
        "@pulumi/cloud-aws": "^0.30.1",
        "@pulumi/pulumi": "^3.0.0"
    }
}```

what does `pulumi stack output` show? everything looks okay now

```[nix-shell:~/dev/lvtia/aws/aws_ts]$ pulumi stack output
Please choose a stack: dev
 Current stack outputs (0):
    No output values currently in this stack```
Can it be that during a few tests the AWS env got corrupted (and there I mean in full desync with pulumi stack) ?

No standard pulumi example gets installed, actually. Everything fails for the same error ...

I would clear out your plugin cache `pulumi plugin rm -a` then start again by reinstalling the your node modules
