Context is loaded at the import time of the library unless otherwise explicitly overridden which means the secret should be set prior to the import of prefect In this case I would recommend setting it outside your script e g ```export PREFECT CONTEXT SECRETS SLACK WEBHOOK URL= ``` or it could be placed in your `~ prefect config toml` under ``` context secrets SLACK WEBHOOK URL= ```

yea adding to what < josh> said Setting an environment variable via os will only work if you fork spawn a new process If you want it to be all in the script you can also add the secret directly to context in place of your os call
