This is the error message.

The 'start index' for function 'substring' must be equal to or greater than zero and must be less than '3' which is the length of the string.

Start Position Expression:  add(outputs('Find_text_position')?['body'],4)

    On the same string value?  The error would be completely dependent on how long the original string is and where the text you are searching for is located.

    You're adding 4 to the position of specific text in the string when there are only 3 characters left in the string.  That isn't a new issue.  You've never been able to use an index position beyond the end of the string.
