When testing locally, it works.

Let me look this over! Thanks!

If that works too, could you run this from the machine that hosts your XO?
Replace <TOKEN> with the token that you put in the Netbox plugin configuration:

curl -skv -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" "https://fw-dea12.domain.tld/api/extras/custom-fields/"

Just to say that yes the link is accessible.

If I open said link on the browser I get:

Hi there and thank you for your reply.
Well, the error messages aren't exactly equal so to say.

In the image below you can see the result of testing before the XO update was completed (namely the Oct 24 11:11 test was made after update BEFORE reboot/xo restart and 11:16 was after).
So the error message does change slightly.

/#/settings/plugins?s=netbox

Netbox 1.3.0

I restarted the whole server before actually testing.

the screenshot above was immediately after the build but before the reboot. Was focused on the commit.
Then rebooted, tested, error.

XO up to date now

Something appears to be wrong because the version of xo=server is way off (should be 5.124.0)

XO up to date now

Still giving the same 400 bad request error

About merging it: sadly, we do not have the resources to check/investigate and solve build issue on any other platform than x86 at the moment. I prepared a Arm instance for Florent last year, but we have many other things with a higher priority right now. However, contributions are welcome

edit: it seems related to fuse-native in your case

Its an ARM instance.

https://xcp-ng.org/forum/topic/6344/libfuse-so-error-adding-symbols-file-in-wrong-format

About the dep, I don't know, on what kind of machine you are building it?

Is this related to the fuse arm dependency?

unfortunately not progressing
