Unable to access environment variables in an agent

Posted on by ND-20051403-0

Hi,

I have created a string environment variable to store a storage account name in my solution in Power Apps. I have an agent in the same solution where I want to access the environment variable. But I do not see the variable under the Environment or System variables section. I have tried to remove and readd the variable to the solution and try this in incognito browser.

What am I missing?

Thanks,

Nihar Dalai.

Why You Don’t See the Environment Variable

Environment variables created in Power Apps solutions are not always immediately available to Copilot Studio agents or flows.

Sometimes, there is a delay in propagation, or the variable is not surfaced in the Copilot Studio UI.

Only environment variables of type “Environment variable (string)” and set to “Current Value” are accessible at runtime.

If the variable is not referenced in a flow or app, it may not appear in the variable picker.

What to Do
Check Variable Type and Value

Ensure the variable is of type “Environment variable (string).”

Set a “Current Value” (not just a default value).

Publish All Customizations

In Power Apps, go to your solution and “Publish all customizations.”

Refresh Copilot Studio

Wait a few minutes, then refresh Copilot Studio (or try a new browser/incognito window).

Reference in a Flow

If you still don’t see it, try referencing the environment variable in a Power Automate flow in the same solution. Sometimes this “activates” the variable for other components.

Check Permissions

Make sure you have the right permissions in the environment.

Hi @CU29041745-1,

Environment variables in Copilot Studio don't appear automatically in the Environment/System variables section until you reference them inside a topic. That's likely why you don't see it.

Here's how to access it:

1. Open a topic in your agent
2. Add a Set variable value node or any node that uses variables
3. Open the variable picker and look for the Environment section your variable should appear there
4. Once referenced in a topic, it shows up in the Variables panel on the right side

A few things from Microsoft docs to check:

Environment variables are read-only in Copilot Studio you can read them but not modify them from within the agent. Make sure you have a Current Value set on the variable in Power Apps (not just a Default Value). Default Value alone is not always used at runtime.

Also confirm the environment variable is in the same solution as your agent. If it's in a different solution, it may appear in the picker but won't reliably deploy to target environments.

After making any changes to the environment variable value, you need to republish the agent for the new value to take effect at runtime.

Thank you both for your response. I have tried all the below and still no luck.

1. I have confirmed it is a text environment variable with both a default value and a current value.

2. It is in the same environment and solution as my agent.

3. I have published all customizations after creating the variable.

4. Waited a few mins and tried to access environment variables in an incognito browser.

5. Tried accessing it in the Greeting topic of the agent as below. Dont see it.

6. I can see the environment variable as a parameter in a flow. Tried using it there. Came back to the topic and still dont see it.

Any thoughts what might still be missing?

Thanks,

Nihar Dalai.

Hi CU29041745-1
Thanks for confirming all the checks. Since the environment variable is visible in Power Automate but not in Copilot Studio, this may be a Copilot Studio sync/propagation issue rather than a configuration problem.

You can try:

Creating a new text environment variable and checking if that appears

Testing with a new agent in the same solution/environment

Republishing the agent after re-adding the variable

If the issue still persists, it is likely a product limitation/UI issue in Copilot Studio, especially since the variable is already accessible in flows.

Thanks for your response Prasad. I have tried all the steps you mentioned and still no luck.

It looks like a big limitation. We are trying to deploy to Prod and I cannot use my blob storage connectors as tools in my agent because the blob storage account differs per environment. I am pretty sure there must be others using Copilot Studio facing similar issues.

Would you know if this is something on the cards for the Copilot Studio Dev Team?

Regards,

Nihar Dalai.
