Description:

I'm experiencing a strange issue with environment variables in a managed solution after migrating from a Dev environment to a Test environment.

Setup:

Power Automate Desktop v2.65.145.26040
Managed solution exported from Dev and imported into Test
Execution mode: Attended, triggered manually outside the editor

The problem:

When I run the desktop flow manually outside the editor in Dev environment or inside the PAD editor, it works correctly and retrieves the environment variable without issues.

However, when I run the same flow manually outside the editor (attended mode), it fails with the following error:

No environment variable was found with schema name "deb_EVTemplateRelatorioConsultaEcac" and ID "84273257-ad1c-f111-8341-7ced8db0fcbc"

Root cause investigation:

After checking, I noticed that the GUID in the error message (84273257-ad1c-f111-8341-7ced8db0fcbc) belongs to the environment variable in the Dev environment, not in Test. The variable exists in Test and has a value assigned, but with a different GUID.

This suggests the flow has the Dev GUID hardcoded in its definition, and only resolves correctly by schema name when running inside the editor session.

Questions:

Why does the PAD runtime resolve the environment variable correctly inside the editor but fail outside of it?
Is there a known issue with environment variable GUIDs being hardcoded in desktop flow definitions when exported as managed solutions?
What is the recommended approach to ensure environment variables are resolved by schema name (not by GUID) when running in attended mode outside the editor?

Any guidance would be appreciated. Thanks!

Using flows

Hi @VA-24031227-0,

This is a known behavior / limitation in Power Automate Desktop when desktop flows inside managed solutions reference environment variables and are executed outside the PAD editor.

Inside the editor, PAD resolves environment variables by schema name using live Dataverse context.
Outside the editor (attended runtime), PAD resolves environment variables by GUID captured at design time.

After moving the solution from Dev --> Test, the environment variable GUID changes, but the desktop flow still references the original Dev GUID, causing runtime failure. So this is not a configuration mistake on your side, it’s a resolution mismatch between editor vs runtime.

Practical recommendation
For production‑grade ALM with Desktop Flows:
Use environment variables only in cloud flows
Pass values explicitly into desktop flows
Or rebind variables post‑import before runtime use
Until PAD changes runtime resolution behavior, this is the safest pattern.

1) Why does the PAD runtime resolve the environment variable correctly inside the editor but fail outside of it?

Because:
Editor = dynamic resolution by schema name
Runtime = static resolution by stored GUID

2) Is there a known issue with environment variable GUIDs being hardcoded in desktop flow definitions when exported as managed solutions?

Yes, this is a known limitation of Desktop Flows in managed solutions.
Desktop flow packages currently persist environment variable references with their Dataverse IDs.
This behavior has been observed by multiple customers after Dev --> Test / Prod promotions.

3) What is the recommended approach to ensure environment variables are resolved by schema name (not by GUID) when running in attended mode outside the editor?

Rebind environment variables after import
After importing into Test:

Open the desktop flow in the Test environment
Re‑select the environment variable in the flow action
Save the flow
Publish

This forces PAD to update the stored GUID to the Test environment variable.
