Avoid implicit try-catch

[iromli]

The following code makes debugging a little bit harder:

try:
    # do something
except:
    return False

We should explicitly specify the exception, for example:

try:
    # do something
except ValueError:
    return False

or

try:
    # do something
except Exception as exc:
    logger.debug(f"Uncaught error={exc}")
    return False

Given this new style try-catch, we can avoid errors like NameError, SyntaxError, etc. (which should be fixed by developer) or any runtime errors.
