OneDriveSharePoint shortcut with library variables error

[hvdbunte]

I try to dynamicly change the target subpath of the onedrive sharepoint connector for my environments (dev/test/ etc) So I would like to replace the target subpath with a library variable.

my variable value:

But when I change the target subpath value to the above library variable I get below error:

Can somebody explain if this is still an issue because the connector is still in preview? Or how I could fix the syntax?

Kind regards,

Hi @hvdbunte,

This looks more like a current limitation of Variable Library support in certain shortcut properties than an actual syntax issue on your side.

The behavior you’re seeing is pretty consistent with what we currently observe with OneDrive/SharePoint shortcuts:
variables are supported in some contexts, but the target subpath does not always seem to get properly re-resolved after interpolation.

In other words :

The static path works, but as soon as a Variable Library value is injected into the subpath, the shortcut validation can fail before the variable is fully resolved.

And yes, there’s already quite a bit of community feedback around this behavior.

A few possible approaches :

1. Manually run "Update All Variables"
   In some cases, you need to force a variable refresh on the Lakehouse side for the shortcut to pick up the latest values.
2. REST API / automated provisioning
   Probably the most robust approach for multi-environment setups (dev/test/prod) : recreate the shortcuts dynamically with the correct subpaths per environment.
3. Terraform / IaC
   Also a very clean option if you’re already industrializing your Fabric deployments.
4. Variables + manual refresh
   Can work… with a bit of friction 😅

Curious to know : are you staying UI-only for shortcut management, or are you also testing the Fabric API approach? 👀

Hi @Tamanchu ,

Thank you for the solutions, I have to dive in the api's and see if that could work for us.

Currently we are starting with usting sharepoint so I don't have much experience yet how to integrate this properly into our test/acc/prod. So I started with the UI to see how this could work.

Can you maybe show an example of how you use the rest api for automated provisioning? 

Kind regards

Hi @hvdbunte ,

Thank you for contacting the Microsoft Fabric community forum.

Yes, I think the API approach will fit much better once you start separating dev/test/prod environments. From your screenshots and the 400 error, it looks less like a syntax mistake and more like a limitation of variable substitution for SharePoint shortcut subpath values in the UI. The static path works, but the validation seems to fail when the variable is injected. With the REST API, you can simply generate the correct path during deployment instead of relying on UI interpolation.

Example:

POST https://api.fabric.microsoft.com/v1/workspaces/{workspaceId}/items/{lakehouseId}/shortcuts
{
"path": "Files",
"name": "dev",
"target": {
"sharePoint": {
"connectionId": "<connection-id>",
"location": "https://contoso.sharepoint.com/sites/project",
"subpath": "General/import/dev"
}
}
}

Then in your pipeline/script you only swap the environment value:

General/import/dev

General/import/test

General/import/prod

Also, Please refer to:

Hi @v-menakakota,

Thank you for the detailed reply. I will have to test en implement this. But it looks very promising.
