Note: I know this is previously logged - but it says its fixed when its not

[jooj123]

Also (not sure its part of same issue) it doesnt matter what warn or error values I put into expectations - it doesnt warn or error anymore with this latest version

[denar90]

Error is fixed in v4.2.1. Regarding warn or error. Do you wanna pwmetrics throw it or just write in console?

error I got running example from recipe
