hey i get this error in google pagespeed connected to the Klarna plugin but im not sure what its related to The page I need help with: [ log in to see the link] HI! Client ID is required if you would want to use any of Klarnas boost features such as Klarna Express Checkout, Sign in with Klarna or On site Messaging. It can be fetched from the merchant portal . If you would not want to use them on your page you can disable them in the configuration for the plugin (in woo admin) and the message should disappear. Kind Regards, Awa from Klarna okay thanks just wanna say the issus dit not go away by disabling the function only by adding the api key in the backend Hi @dennisr1 , That is strange, when replicated on our side the issue only appears if Express Checkout, Sign In With Klarna or On-Site Messaging is enabled while the client ID under credentials section is missing. If client ID is filled in or if the boost features are disabled – the issue disappears. If you would like, please provide logs along with exact replication steps so we can see why this is not the case on your side. /Awa from Klarna
