The length of substring can't be longer than '1962' which is the length of the source string.

Hi @Anonymous,

Like the error mentions. The substring function expects the following format

substring('<text>', <startIndex>, <length>)

The last part, the length cannot be longer than the actual length of the source string. That is what the error means.

If you don't know or want to use a length calculation at all I would suggest to use a slice function instead. That function does not require a length.

slice('<text>', <startIndex>, <endIndex>?)
