EntityFrameworkCore Scaffolding: Could not find type mapping for column 'TEST_TABLE.VAL' with data type 'NUMERIC(16,2)'

[Edward72]

I try to scaffold test_db:
Scaffold-DbContext "Server=x.x.x.x;Database=test_db;user id=SYSDBA;password=masterkey;Dialect=3" FirebirdSql.EntityFrameworkCore.Firebird -Force -Verbose -OutputDir Models
I get the following error:
Using project 'FBNetCoreApp'.

Build succeeded.

To protect potentially sensitive information in your connection string, you should move it out of source code. You can avoid scaffolding the connection string by using the Name= syntax to read it from configuration - see https://go.microsoft.com/fwlink/?linkid=2131148.

Could not find type mapping for column 'TEST_TABLE.VAL' with data type 'NUMERIC(16,2)'. Skipping column.

As a result, class TestTable in TestTable.cs has no field VAL. What could be the problem?
