Unable to share Code app with users

[Max6x6x]

Hi All,

Here is my usecase:

• I have a Production, managed environment

• i have 2 solutions:

  • Solution A: 20 custom tables, 2 security roles, 20 cloud flows (for BPF and sharepoint file management), 1 Code App developed with Claude MCP, plugins, skilss...etc
  • Solution B: 14 custom tables, 3 security roles, 14 cloud flows, 3 connection references, 1 Code app and 1 canvas app (canvas app reading and writing a couple of the tables)

• 8 users: with assigned Powerapps Premium license (and powerautomate premium licence), plus assigne "Basic user" sec role and the custom sec roles needed for one-one app.

What's the problem:

• If i open the code app (ofc) everything works properly
• if any of the users opens the code app, the "menü bar" and some of the UI elements are visible and clickable, BUT for the rest the following error pops up -> "The backend request failed with error code '400'" ..... failed to retrieve toke for source......"

What i did:

• I've deleted and reshared the app multiple times
• they created own "dataverse" connections
• i went trough a platea of setups in admin center
• i tried to "share the connection" that i created, but is on my name and says that i can share it only with a service principal.

Question: hooooooow can i make it work for the users? This is a try with code app, previously i was building a model driven on top of these and i deleted it, since the code app had mor UX/UI flexibility. back in the stone age, model driven was needing only a "share" and that the users had license, sec role and that's it.... Am i missing something?

For a model-driven app, you share the app directly with a security role: users with this security role will have access to both the app and the data.

For canvas and code apps, you share with a team (or user), and people in that team can access the app. They obviously still need access to the underlying data through a security role.

Your issue seems to be with the security role, not the code app. To test this, I would suggest creating a disposable model-driven app with the same table, sharing it with a security role, and seeing if users can view the required data. If not, it is definitely a security role issue.

Code apps adhere to Dataverse's security setup meaning that the end users require relevant access to the underlying tables.

George's answer seems to be the correct answer; this definitely looks like an issue with permissions related to data and not the app. If you are still running into this problem, please create an issue that includes the session ID or send us an email with a network trace so that we can look further into this: pacodeapppreview@microsoft.com
