Strange errror "provider FAILED" when trying to format ERB files

[goldelehr]

Hello,

I wanted to try the ERB Formatter plugin for VS Code and as soon as I call "Format Document" on an ERB file I get the following error and a stacktrace in the Extension (Host) Output tab in VS Code.

[error] [elia.erb-formatter] provider FAILED

I couldn't install the VS Code Ruby extension as it is deprecated as of now but instead i'm using Shopify's Ruby LSP.

Thanks for your help!
