[Bug]: createToken() should have better exception error messages

[Azhrei]

Describe the Bug

createToken() has many, many options, but when something goes wrong, a single generic exception message is generated. The message should be directly related to the field that caused the exception.

(It would be nice if all parameters could be validated and references to all failing fields were provided, but that is likely to make the exception message excessively long.)

To Reproduce

See this Discord thread by @tdufor sample code and some discussion.

Expected Behaviour

When there's an error accessing a particular resource, say so, whether it's the name parameter, tokenImage parameter, or something else. Also report parameters that have invalid values by including both the parameter name and the list of valid values (or range of valid values, as appropriate).
