I keep getting this when I have modular avatar in my project and I try to play test it or upload
uh you cut out too much on that screenshot.
The top half is just explaining that vrc build pipelines found an error
Usually it also says what type of error it is though, which is useful info. The most common being “null reference exception”.
Was it also the only error in the list, or were there others if you scroll the console up?
Looks like a third party tool you have installed had an issue, but this small cropping doesn’t give enough info.
This was the only error and its actually the whole error message, just partially cut the top by half the text
Your issue does mention NDMF and possibly modular avatar.
Can you precise if this happened after an update or at the first upload test of your avatar ?
And add to that the list of potential packages / assets you use, maybe you are having a compatibility issue or a component that is wrong
The issue has been fixed, thanks all for helping the best you can.
