Dictionary exception is thrown in EFCore.BulkExtensions.PostgreSql/SqlAdapters/PostgreSql/PostgreSqlAdapter.cs

EFCore.BulkExtensions.PostgreSql/SqlAdapters/PostgreSql/PostgreSqlAdapter.cs

The function:
static object? GetPropertyValue(DbContext context, TableInfo tableInfo, string propertyName, T entity)

Throw exception due to value is not found in dictionary

The problem in the function is follow part:

        object? propertyValue = entity;
        string fullPropertyName = string.Empty;
        foreach (var entry in propertyName.AsSpan().Split("."))
        {
            if (propertyValue == null)
            {
                return null;
            }

            if (fullPropertyName.Length > 0)
            {
                fullPropertyName += $"_{entry.ToString()}";
            }
            else
            {
                fullPropertyName = new string(entry.ToString());
            }

            propertyValue = tableInfo.FastPropertyDict[fullPropertyName].Get(propertyValue);
        }
        return propertyValue;

Eg propertyName is "id"
var entry in propertyName.AsSpan().Split(".") generates a range object and range object to string in follow code
fullPropertyName = new string(entry.ToString()); gives "[0..2] not "id"

I made follow change to the code just to get it to work.
foreach (var entry in propertyName.Split(".").AsSpan())

However I dont know what other implication it will give for more complex projects.

Same Problem.

I'm only using once --> await context.BulkInsertAsync(entities, bulkConfig, progress, cancellationToken: cancellationToken);

With Version 9.0.2 and EFCore 10 no Error.
I have Warning: [NU1608] Detected package version outside of dependency constraint: Npgsql.EntityFrameworkCore.PostgreSQL 9.0.4 requires Microsoft.EntityFrameworkCore (>= 9.0.1 && < 10.0.0) but version Microsoft.EntityFrameworkCore 10.0.0 was resolved.

But now Error at Runtime.
