Web interface refuses to load Traccar 4.9

When I enter the web interface I get infinite loading.

Browser console shows this:

Uncaught ReferenceError: ol is not defined
    <anonymous> https://***.com/app.min.js:302
    ExtJS 9
    <anonymous> https://***.com/app.min.js:294
app.min.js:302:273

Can anything be done about it? Our traccar instance wasn't touched for months. I have to avoid updating Traccar for now, unfortunately.

Upgrade?

We presented the same error for approximately 2 hours the error apparently is because this plugin does not load

https://cdn.jsdelivr.net/gh/openlayers/openlayers.github.io@master/en/v6.1.1/build/ol.js

is it necessary to update the system?

The URL is working for me.

If it still doesn't work, I would recommend upgrading.

This link returns the following for me:

Package size exceeded the configured limit of 50 MB. Try https://github.com/openlayers/openlayers.github.io/tree/master/en/v6.1.1/build/ol.js instead.

It's 154 kB in size. I wonder if that's an issue with jsdelivr.

How to make Traccar use this file locally instead of CDN? Clearing browser cache didn't work for me unfortunately.

You can update load.js file. In fact you can probably update it to the latest version that we have.

Thank you, the load.js from the repo works.

where is it located? load.js

Sorry for late reply - download this file:
https://raw.githubusercontent.com/traccar/traccar-web/65af8bad51851ff7f15319d5ce14ff24697aaded/web/load.js
and replace the old load.js in /opt/traccar/web/ (or anywhere else you have traccar installed)

Thanks ! work fine

Thank you, worked for me as well
