I'm trying to get this running and getting an error.

Error
Action 'Remove_the_Header_Info_from_the_Power_Apps_Image_Value' failed
Error Details
The 'start index' for function 'substring' must be equal to or greater than zero and must be less than '0' which is the length of the string.

    hi @damian_green  that what message is trying to said is that you have a string that instead of content info is 0. 

     

    Here's an example:

     

    text: Example Test

    when you do length(Text) the result is 12

     

    then substring will need to know what is the start of your text and the end in numbers and then extract whatever you are trying to.
