I have come across this error that I think may be and out of bounds error, but im not sure. I was wanting a second opinion on it. An error has occurred while handling the request.

Hello, does this $WeekSummary/Utilization1 has a value?
The substring is starting at 0 and ending at 1, but the resulting length is 0, so, I’m assuming the string has no value in the first place.
java.lang.StringIndexOutOfBoundsException: begin 0, end 1, length 0
The substring function throws an error if:
The start position of the substring is after the last character in the string
The desired length of the result is longer than the substring
Let me know if this helps.
Best regards,
João

Hi Reece Heald,
Yes the error String Index out of bound Exception.
Length of the string is not matching with the sub string index. For example string value 'Dinesh', total length is 6. The substring function is looking more than index 6.
I would suggest you to create your SubString, Max, Length Functions in Separate Variables and check the values, you will get an idea what are the end values and adjust your expression
accordingly ( also Add empty check for your string and object and if not empty then proceed with your Expression).
