Why am I unable to access secrets from a web app with MATLAB Web App Server R2024a?

I developed a MATLAB app that fetches data from a database using the secrets functionality. This works successfully in my local machine. However, running the same app as a web app throws the following errors when trying to access the secret:

2024-09-15 15:26:44 webappSendGetSecretCommand :failure: User is not authorized to access this data
2024-09-15 15:26:44 Error using getSecret (line 10)
2024-09-15 15:26:44 No secret value found for secret name 'mySecret' in the vault.

I have followed the documentation to set up my MATLAB Web App Server with all of the secrets from my local MATLAB session. I have also enabled SSL and authentication (OIDC) on my Web App Server. 

Why am I unable to access secrets through my web app?

If your server is set up to use authentication, you must create a secrets access control file (webapps_secrets_acc_ctl.json) before you can access secrets within web apps. From the documentation:

        If server authentication is enabled, then secret access control is enabled by default, and an authenticated user will have no access to any secrets unless specified with a policy.

 

You can follow the instructions in the linked documentation above to create the webapps_secrets_acc_ctl.json file to resolve this.
