The execution of template action 'For_each' failed: the result of the evaluation of 'foreach' expression '@items('Apply_to_each')?['Birthday']' is of type 'String'. The result must be a valid array.

    Hi,
     
    Can you share part of your flow here please?  Please paste in screenshots vs adding as attachments - you will get a lot more engagement with pictures of the flow and error.
     
    I'm sure this can be solved quickly.

    It looks like the error message indicates that the Apply to each action is being used on a value that is not an array. The expression @items('Apply_to_each')?['Birthday'] is returning a string (single item) instead of an array (multiple items), which is causing the failure.

    To help you better, could you please share a screenshot of your flow, specifically showing how the action that is failing is configured? This will allow us to see the context and provide more precise guidance.

    In general, if the Birthday field is expected to be a single value rather than an array, you might not need the Apply to each action. Instead, you can directly reference the Birthday field without wrapping it in a loop.
