Add code to print the offending string that is failing and run it again. Alternatively, make sure all of the dict keys in your yaml obey the key character content restrictions.

Honestly using a debugger for this makes little sense.

Can you post your configtx yaml?
I can take a peek as well.

Thanks Dave for opening the bug. Now that's what a helpful response is.
Close... some key within the [Group] config has an illegal character. You can see the valid characters here:
I suspect it is this one - keys must "Contain only ASCII alphanumerics, dots '.', dashes '-'"
Unfortunately it looks like the underlying root cause is not printed in the error message. I've opened a bug on your behalf so that the next person to hit it gets a better error message:
For cryptic errors, please do open bugs so that they can get improved.

"Illegal characters in key: [Group]"
I'm guessing it doesn't like the brackets in "[Group]"
Tells you exactly where the "Failed validating bootstrap block" problem is.
A debugger would absolutely not tell you much more.

With these kinds of errors, its not possible to know what caused it just by looking at trace above and I am helpless what to do next. So I am wondering if there is a way for me to log into the container and be able to debug with a debugger
(like the way we could do using gdb or ddd)? Would appreciate step by step instructions please which can be followed by a poor man like me (not hand wavy answers)
