Which issue(s) this PR fixes:

None

What this PR does / why we need it:
We recently encountered a weird error showing that:

value must be a string or a number: (value.class)"

After digging into the source code, I finally realized that I passed nil into the parser but the message was quite confusing.

From my perspective, I thought (value.class) should actually be (#{value.class}), which showed the class name of the value. In my case, it will be (NilClass), which should be clear for users to understand.

Docs Changes:

None

Release Note:

None
