I remember someone has brought this up on discord recently, and he fixed it by using an older paper build (can't remember which one).
You can try doing the same as for now until it gets fixed.

That was me lol. But I can't do that unfortunately since I went to 1.15.2. And I can't go back to 1.15.1.

I have just temporarily removed the placeholders from my server for the time being.

I am using java 8 right now. Could updating my java version fix this?

Hello, I got the same issue here, and I found the plugin MythicMobsExtension cause the problem, which supports javascript as well.
The Javascript on PAPI works well as I turned JS support off in MythicMobsExtension's config.
Hope this helps.

Thanks, I don't have mythicmobsextension, so there must be another plugin causing problems. Weird that it was working before.

I had the same problem but i solved it by switching to java 11

Chatcontrol 9.0.4 will causes the same problem

I'm also having this issue in 1.15.2 with PAPI 2.10.9. I don't have MythicMobsExtension but I do have ChatControl Pro 8.7.3.

I personally believe this is probably caused by how ChatControl Pro handles the placeholders and less by PlaceholderAPI or this Expansion itself.

If it works without CCP then that plugin is clearly the cause of the issue and you should nag the dev about it. He can always join the HelpChat Discord for some help. https://discord.gg/helpchat
