[namireddy]

Is this feature request related to a new rule or cfn-lint capabilities?

Describe the feature you'd like to request

Fn::FindInMap, When the nested level depth is greater than 2 , error E1011 is thrown with a message xxx is too long (3).
Sample:
Mappings:
MyCustomMap
Level1:
Level2:
"key":"value"

Error message when cfn-lint is run
E1011 ['MyCustomMap', 'Level1', 'Level2',' Key'] is too long (3)
E3024 ['MyCustomMap', 'Level1', 'Level2', 'Key'] is too long (3)

Describe the solution you'd like

Can the message be improved, to say "FindInMap only supports up to two levels of nesting for map lookups"

This is the result of the maxItems keyword

cfn-lint/src/cfnlint/jsonschema/_keywords.py

Lines 322 to 326 in 8164ed9

	def maxItems(
	validator: Validator, mI: Any, instance: Any, schema: dict[str, Any]
	) -> ValidationResult: # pylint: disable=arguments-renamed
	if validator.is_type(instance, "array") and len(instance) > mI:
	yield ValidationError(f"{instance!r} is too long ({mI})")

We can alter the wording inside functions or alter the wording for any occurrences of maxItems. The error message from the service would look like expected maximum item count: 3, found: 4. Then we could add a function prefix like Fn::FindInMap expected maximum item count: 3, found: 4

What I like about this is that it removes the instance from the results which can get long.
