Interestingly enough, when I call the Python script from the Go app, it works fine. Given the following Python script named op.py:

```

!/usr/bin/env python

import subprocess

subprocess.run(["op", "item", "get", "DocSend", "--format=json"])
```

and the following Go app in the same directory:

```
package main

import (
"encoding/json"
"fmt"
"log"
"os/exec"
)

func main() {
op := exec.Command("/usr/bin/python3.11", "./op.py")
//op := exec.Command("op", "item", "get", "DocSend", "--format=json")
out, err := op.Output()
if e, ok := err.(*exec.ExitError); ok {
log.Fatal(e, ": ", string(e.Stderr))
}

fmt.Printf("%s", out)

var item map[string]interface{}
if err := json.Unmarshal(out, &item); err != nil {
    log.Fatal(err)
}
fmt.Println(item["fields"])

}
```

...it works fine, the output gets printed. I can test that it is being printed by the Go app and not by the Python script because if I remove the fmt.Printf(...) and below, nothing gets printed.
