requestModel / joaat Errors on Qbox

If you run Qbox (qbx_core), you may see one of these in your client console (F8):

@ox_lib/imports/requestModel/client.lua:14: bad argument #1 to 'joaat' (string expected, got nil)

[ox_lib] [WARN] lib.requestModel received invalid prop data from resource 'qbx_core' (table is empty)

Despite naming requestModel, this is not caused by our scripts. It is a version mismatch between ox_lib and qbx_core, and it can appear with any resource that uses the Qbox progress bar compatibility layer.

What causes it

Qbox ships a QBCore compatibility layer for progress bars (QBCore.Functions.Progressbar). In qbx_core v1.23.0 — currently the newest tagged release — that layer always builds an empty prop table and passes it to ox_lib, even when no prop was requested.

ox_lib v3.37.2 added prop validation that rejects an empty table. The empty table then fails validation, and the progress bar is cancelled before it ever appears — which is why the action itself silently fails.

The fix

Update ox_lib

Download ox_lib v3.39.0 or newer:

github.com/overextended/ox_lib/releases/tag/v3.39.0

v3.39.0 downgraded the failed validation from an error to a warning. Progress bars work normally again.

TIP

This is the only step most people need. The remaining warning is cosmetic — it prints to the client console only, never to your server console, and nothing is broken.

Enable ox_lib progress bars in the script

Many of our scripts include a bridge switch that makes them call ox_lib directly instead of routing through the Qbox compatibility layer. Turning it on avoids the problem entirely — both the error and the warning — on any ox_lib version.

Open bridge/client.lua in the script and set:

local EnableOX = true

Then restart the resource. The setting is read once when the script loads, so a live edit will not apply until you restart it.

TIP

Some of our scripts already ship with this enabled, so you may find it is already set to true. If there is no EnableOX in bridge/client.lua, that script uses a different bridge setup — updating ox_lib as described above still resolves the error, or open a support ticket and we will take a look.

Remove the warning entirely (optional)

The warning comes from qbx_core, and it is already fixed there — but only on the main branch, not in any tagged release. The fix is commit 30d0ee2 (19 May 2026).

WARNING

v1.23.0 was tagged in April 2025, so moving to main is roughly 62 commits of core framework changes — not a drop-in hotfix. Only do this if you want the warning gone across every resource on your server, and test it first.

Version reference

ox_lib	qbx_core v1.23.0 (latest release)	qbx_core main
Below 3.37.2	Works	Works
3.37.2 – 3.38.0	Error — progress bars fail	Works
3.39.0 or newer	Works, prints a warning	Works, no warning

TIP

Downloading the newest release of a script always requires the newest release of ox_lib. We recommend keeping ox_lib up to date regardless of this issue.
