Hi, I am following this instruction:

[![](https://global.discourse-cdn.com/shotgunsoftware/original/2X/9/9884f9f30df773de6b9d439f1835ae313e2cb6e5.jpeg "Developer Training - Shotgun: Creating, Testing, and Debugging Action Menu Items") ](https://www.youtube.com/watch?v=u3u8pL9o-as)

but I am getting this error: (vscode)  
[2024-02-28 16:49:02,342] ERROR in app: Exception on / [GET]

127.0.0.1 - - [28/Feb/2024 16:49:02] “GET / HTTP/1.1” 500 -

any ideas?

i did set both like so:  
set FLASK\_SCRIPT\_NAME=“test\_sg\_ami.py”  
set FLASK\_SCRIPT\_KEY=“4ckyuwC-vcmkahunxkksrgqkv”

Where did you set the varables?  
Because it seems like your script can’t access them.

hi Ricardo,  
I set them here in the python file:  
script\_name=os.environ[“FLASK\_SCRIPT\_NAME”],  
api\_key=os.environ[“FLASK\_SCRIPT\_KEY”],

as well as in Terminal in vsCode by doing:  
set FLASK\_SCRIPT\_NAME=“test\_sg\_ami.py”  
set FLASK\_SCRIPT\_KEY=“4ckyuwC-vcmkahunxkksrgqkv”

regards,

</div>

i can get it running with following:  
script\_name=“test\_sg\_ami”,  
api\_key=“4ckyuwC-vcmkahunxkksrgqkv”,

but not how the channel instructed:  
script\_name=os.environ[“FLASK\_SCRIPT\_NAME”],  
api\_key=os.environ[“FLASK\_SCRIPT\_KEY”],

thoughts?

1. Please don’t post your script name and key on any public forum, a bad actor would now only need your Shotgrid URl to gain admin access to your site.  
You should invalidate/remove the script user immediatly and recreate it.

2. 

```python
script_name=os.environ[“FLASK_SCRIPT_NAME”],
api_key=os.environ[“FLASK_SCRIPT_KEY”]

```

This refers to searching the environment for these keys and their value.  
This only works if you set these environments on the machine or on the fly.  
If you run this from VS Code then either you need to ensure VS code sets these when you run your file or the machine itself has these environment variables set.

Also, not sure why you have a comma after the first line, you should remove that.
