Found '⁨{{placeholder: String, editable: boolean}}⁩', but there is no field called '⁨ boolean⁩'
I could not find a solution of this problem and i do not know what to do and how to fix this.
Any help please, i cannot do interactive presentation.

    The link you have sent I ave already pay attention before calling you.

    It is not applid for my situation. And in the card i found no error and
    the syntaxy is correct.

    I do not know any other soulution then unistall anly from my computer
    because it does not funcion right. Even the add on interactive for
    languages is not accepted. I have installed even the latest vrsion of
    anki but still have the same message:

    Found '⁨{{placeholder: String, editable: boolean}}⁩', but there is no
    field called '⁨ boolean⁩'

    What is this field 'boolean' that cannot find?

    I do not know!

    Hi Roberto, I had similar problem with interactive template. I found out solution and it works. Delete all this line: {placeholder: String, editable: boolean}}⁩..." on both: Front And Back Template. And then replace line with this (Don't forget to paste this on both: Front and Back template):
    * @param {placeholder: String} params
    * @param {editable: boolean} params

    Hope this help you,

    Thank you, Lydia.
    This fix worked for the "Interactive Demo-version" theme.
