Hello @Gsk,

You might want to provide your blocks/AIA file so we can help you further , see How to ask a question (open new topic) :slightly_smiling_face:
However, this error usually happens when you input a number to a block's parameter that expects you to input a Button component. ( ex: Any Button blocks, or an extension, etc.. )
