Missing required environment variable: RC_API_SECRET_HOST when using Vault

I followed an example from Robocorp and I’m pretty sure no error or tipo so far but it’s keeping asking me for : RC_API_SECRET_HOST when I’m starting the robot with the command “rcc run”

I saw RC_API_SECRET_HOST as URL to Robocorp Vault API in the documentation but as I’m in local environment and don’t need to access the cloud or store something in it.

Do I miss something here ?

Thanks for your feedback.

You need to set up local vault to use secrets.


These were the steps I went through :

  • I created a vault.json file that look like in the tutorial :
  "credentials": {
    "username": <myusername>,
    "password": <mypassword>

and put it in : "C:\\Users\\<myuser>\\vault.json"

then I created the env.json file under devdata folder that looks like this :

  "RPA_SECRET_MANAGER": "RPA.Robocorp.Vault.FileSecrets",
  "RPA_SECRET_FILE": "C:\\Users\\<myuser>\\vault.json"

And finally, I requested my credential in my tasks.py robot (Actually, I’m using full python implementation instead of robotframework script)

and it looks like this :

from RPA.Browser.Selenium import Selenium
from RPA.Robocorp.Vault import Vault
from robot.api import logger
lib = Selenium()

secret = Vault().get_secret("credentials")
username = secret["username"] 
password = secret["password"]

So, if I understood, all things are there except creating credentials in robocorp cloud. Something that I don’t want to do.

As I’m newbie, maybe there are things I didn’t catch up yet.

@arcondo.dasilva are you running in terminal with rcc run ? If yes, then you need to pass env.json as an argument for rcc

rcc run -e devdata\env.json

The VSCode Robocorp extension includes devdata env.json automatically if it exists, but when running in terminal you need to include env.json

Here’s some more explanation on the topic by @mika.

Using script from command line with rcc

enter command rcc task shell to open shell into environment
enter command use-robocorp-vault set and follow instructions
include devdata/env.json in a command rcc run -e devdata/env.json

Hope this helps!


This is great. It works!
This is my second day with Robot Framework and it’s pretty impressive. I actually used to use UiPath, but things can change quickly.

Thanks, I can now move foreward
