[MSSQL] Unable to decode typeInfo for SSVARIANT

[DavideD]

A simple select on the information schema:

 select * from INFORMATION_SCHEMA.SEQUENCES

Causes the following exception:

Caused by: java.lang.UnsupportedOperationException: Unable to decode typeInfo for SSVARIANT
	at io.vertx.mssqlclient.impl.codec.DataType.decodeTypeInfo(DataType.java:1042) ~[vertx-mssql-client-4.4.1.jar:4.4.1]

This is the only element we create in the database (although, it doesn't seem to matter):

create table BASIC_TYPES_TABLE (unmapped_column int)

Tested with MSSQL 2022-latest and Vert.x 4.3.8 and 4.4.1
