Dysfonction of auto-completion widget during deployment

Hello everyone,
I built a purchase request process with BonitaStudioCommunity-7.6.3. I use in my first form an autocomplete widget filled with data from a sql server database. In a development environment everything works correctly.
My problem is that when I deploy my process, only users with an administrator profile can have the autocompletion feature in the form.
I’ve done a lot of research and I wonder if this is not a limitation of the Community version. I use the BonitaCommunity-7.8.4-Tomcat-8.5.34 bundle for deployment.
I’ll be happy if someone can help me.

Sincerely

Can you see, using web developer tools from your web browser, if you get a response to one of the HTTP request with the code 403? It’s maybe just a permission issue related to the API you are calling to populate your widget.

If you can share (on Google Drive, Dropbox…) your project as a .bos file it might help me to figure out the issue.

On a side note, if possible I recommend to update to the latest version of Bonita (7.8.4) if you start a new development.
