WebSDK: PARTICLE SYSTEM: Invalid change of parameters

When I try loading AR effects on my website’s canvas element, it will throw the error “PARTICLE SYSTEM: Invalid change of parameters.” This happens most of the time, but sometimes it works. I’m not sure whether it is my code that is the issue or DeepAR’s API.

Hi, are you using our quick-start example. It seems like an issue in your code, I’d need to see what particle system is in place and what changes you’re trying to make to it.
We do have a particle system feature, but it’s not used on most effects, so I would assume you have an unrelated particle system that’s causing the issue.
