Description Manisha Saini 2024-09-18 19:51:19 UTC 
Description of problem:

=======================

In the dashboard, navigate to File → Filesystems → select the "filesystem" → create a subvolume group → create a "subvolume" using that group. On the same page, click "Create NFS export" for the subvolume, fill in the required fields, and click "Create."

A warning appears: "500 - Internal Server Error: 'NoneType' object is not subscriptable."

Despite this warning, the NFS export is successfully created in the backend. You can confirm this by going to File → NFS, where the export is listed.

This warning occurs every time an NFS export is created from a subvolume.
 

Version-Release number of selected component (if applicable):
=================
# ceph --version
ceph version 19.1.1-54.el9cp (c10bee3e898e4ca6f526b1b39f879c9227bf6add) squid (rc)

How reproducible:


Steps to Reproduce:
===================
1. Navigate to File → Filesystems.
2. Select the desired filesystem.
3. Create a subvolume group.
4. Create a subvolume using that group.
5. Click "Create NFS export" for the subvolume.
6. Fill in the required fields and click "Create."

Actual results:
==============
A warning appears, although the NFS export is successfully created and visible on the NFS page.

Expected results:
=================
The NFS export should be created without any warning messages.
