register.ftl and login-verify-email.ftl throw errors

Hello, i made a fully custom theme using others deps as ‘styled-components’ and ‘react-intl’, everything is working well except the register and login verify email where both of those pages throw me the same error:

FTL stack trace ("~" means nesting-related):
        - Failed at: #local value = object[key]  [in template "login-verify-email.ftl" in macro "objectToJson" at line 70, column 21]

this is the code at line 70:

 <#attempt>
                    <#local value = object[key]>
                <#recover>
                    /* couldn't dereference ${key} of object */
                    <#continue>
                </#attempt>

Do you have any ideas of what is going on with this issue, the user cannot register and verify its email (he can only log in) ? Thanks

Ok cool, So, just so you know, it is expected that a lot of errors appears in the Keycloak logs. To converts the .ftl values into a JavaScript object blindly we have to do things that throws. But it’s all-right because every statement that can fail is inside a <#attempt><#recorver> block.
You are not the first one however to be concerned by all the error in the Keycloak logs, maybe I should explain this in the README.

However, back to our problem. As long as you don’t get a 500 when loading the pages and as long as window.kcContext looks alright you should be able to implement the page…

How is your window.kcContext looking on the problematic pages? (You can display it in the devlopper tool of your browser)

It’s alright, even our Keycloak expert got mislead by those errors.
Thanks for reporting
