Failed to upgrade to version 3.0.0

[marichka-spin]

Hello team
We are upgrading our project repos to SpringBoot 4.1.0-M1, and it forced us to migrate to Jackson framework version 3. I tried to upgrade 'json-schema-validator' from version 1.0.83 to version 3.0.0 but I couldn't. Version 1.0.83 allowed to have property "type" of Array type that allows specific type and null
"type": ["string","null"]
But new Schema validator doesn't allow this. And I don't either it is a bug or allowed nulls should be handled differently?
Error that I get:
Caused by: tools.jackson.databind.exc.JsonNodeException: 'ArrayNode' method asString() cannot convert value [...(2 elements)] to java.lang.String: value type not coercible to String at tools.jackson.databind.exc.JsonNodeException.from(JsonNodeException.java:25) at tools.jackson.databind.node.BaseJsonNode._reportCoercionFail(BaseJsonNode.java:655) at tools.jackson.databind.node.BaseJsonNode.asString(BaseJsonNode.java:387) at com.networknt.schema.keyword.BaseKeywordValidator.getNodeFieldType(BaseKeywordValidator.java:89) at com.networknt.schema.keyword.MaximumValidator.<init>(MaximumValidator.java:57) at com.networknt.schema.keyword.KeywordType.newValidator(KeywordType.java:138) at com.networknt.schema.dialect.Dialect.newValidator(Dialect.java:471)

Thank you for any help!
