Entity framework The 'Week' property could not be mapped to the database type 'JSONB' because database provider doesn't support mapping to 'JSONB'

Question

I am trying to use JsonB column using a POCO class in .NET core application using entity framework core 6. I tried to create a database migration (add-migration "AddWeek") It gave me below exception in console

The 'Week' property "WeekData.Week" could not be mapped to the database type 'JSONB' because the database provider does not support mapping 'Week' properties to 'JSONB' columns. Consider mapping to a different database type or converting the property value to a type supported by the database using a value converter. See https://aka.ms/efcore-docs-value-converters for more information. Alternately, exclude the property from the model using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'.

Any help will be greatly appreciated!

Entity class

public class WeekData
{
    public Week? Week { get; set; }
}

JSON POCO class

public class Week
{
    public int[]? WeekDays { get; set; }
}

Entity framework configuration ModelBuilder

public void Configure(EntityTypeBuilder<WeekData> builder)
{
    builder.Property(jc => jc.Week)
    .HasColumnName("week")
    .HasColumnType("JSONB");
}
