[Help-bash] Hello, can someone please help me with this here-document problem?

[Benqzq]

This is the first time I write to the Bash developers directly for help
with Bash. I hope it's okay. I admit I have no plans to make a habit out of
this. I strongly feel this needs a Bash developer take.

I published my problem in the following like in length with markdown.
Please share an opinion on how I could best handle with this:

Thanks anyway, with great appreciation,

[Chet Ramey]

"If the redirection operator is <<-, then all leading tab characters are
stripped from input lines and the line containing delimiter."
