Watch it. I’m helping you on my free time out of the goodness of my heart.
I get that you have many lines. Are you only getting the first line or are you getting the first several but not all? You’re not being very descriptive with what you are trying and what you are getting.
There is a limit to the number of characters that the property can contain. You might be running up against that. Have you considered making a ConfigSource instead of a datasource? That would allow you to have a much larger blob of text.
