• I have provided every relevant configuration, setting, and environment variable used in my setup.
• I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
• I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
• Start with the initial platform/version/OS and dependencies used,
• Specify exact install/launch/configure commands,
• List URLs visited, user input (incl. example values/emails/passwords if needed),
• Describe all options and toggles enabled or changed,
• Include any files or environmental changes,
• Identify the expected and actual result at each stage,
• Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

When uploading files to a workspace model as knowledge and then sharing that model to other users, the query_knowledge tool should work for them and if they have write access, they should be able to inspect the files.

Actual Behavior

For users that got the model shared, query_knowledge doesn't return and if they inspect the knowledge files, they have no content / preview can't be loaded.
For admins or the owner of the model it works fine.

Steps to Reproduce

1. Create workspace model
2. Upload some files
3. Make sure knowledge tool + native tool calling is enabled
4. Share the model to other users (individually)
5. Observe abovementioned "Actual Behavior".
