An exception occurs here:
namespace: Volo.Abp.AuditLogging.EntityFrameworkCore
file: EfCoreAuditLogRepository.cs
method name: IQueryable<AuditLog> GetListQuery

           return DbSet.AsNoTracking()
                .IncludeDetails(includeDetails)
                .WhereIf(startTime.HasValue, auditLog => auditLog.ExecutionTime >= startTime)
                .WhereIf(endTime.HasValue, auditLog => auditLog.ExecutionTime <= endTime)
                .WhereIf(hasException.HasValue && hasException.Value, auditLog => auditLog.Exceptions != null && auditLog.Exceptions != "")
                .WhereIf(hasException.HasValue && !hasException.Value, auditLog => auditLog.Exceptions == null || auditLog.Exceptions == "")
                .WhereIf(httpMethod != null, auditLog => auditLog.HttpMethod == httpMethod)
                .WhereIf(url != null, auditLog => auditLog.Url != null && auditLog.Url.Contains(url))
                .WhereIf(userName != null, auditLog => auditLog.UserName == userName)
                .WhereIf(applicationName != null, auditLog => auditLog.ApplicationName == applicationName)
                .WhereIf(correlationId != null, auditLog => auditLog.CorrelationId == correlationId)
                .WhereIf(httpStatusCode != null && httpStatusCode > 0, auditLog => auditLog.HttpStatusCode == (int?)httpStatusCode)
                .WhereIf(maxExecutionDuration != null && maxExecutionDuration.Value > 0, auditLog => auditLog.ExecutionDuration <= maxExecutionDuration)
                .WhereIf(minExecutionDuration != null && minExecutionDuration.Value > 0, auditLog => auditLog.ExecutionDuration >= minExecutionDuration);

If I write it this way it will solve the problem

           int? _httpStatusCode = (int?)httpStatusCode;
           return DbSet.AsNoTracking()
                .IncludeDetails(includeDetails)
                .WhereIf(startTime.HasValue, auditLog => auditLog.ExecutionTime >= startTime)
                .WhereIf(endTime.HasValue, auditLog => auditLog.ExecutionTime <= endTime)
                .WhereIf(hasException.HasValue && hasException.Value, auditLog => auditLog.Exceptions != null && auditLog.Exceptions != "")
                .WhereIf(hasException.HasValue && !hasException.Value, auditLog => auditLog.Exceptions == null || auditLog.Exceptions == "")
                .WhereIf(httpMethod != null, auditLog => auditLog.HttpMethod == httpMethod)
                .WhereIf(url != null, auditLog => auditLog.Url != null && auditLog.Url.Contains(url))
                .WhereIf(userName != null, auditLog => auditLog.UserName == userName)
                .WhereIf(applicationName != null, auditLog => auditLog.ApplicationName == applicationName)
                .WhereIf(correlationId != null, auditLog => auditLog.CorrelationId == correlationId)
                .WhereIf(httpStatusCode != null && httpStatusCode > 0, auditLog => auditLog.HttpStatusCode == _httpStatusCode)
                .WhereIf(maxExecutionDuration != null && maxExecutionDuration.Value > 0, auditLog => auditLog.ExecutionDuration <= maxExecutionDuration)
                .WhereIf(minExecutionDuration != null && minExecutionDuration.Value > 0, auditLog => auditLog.ExecutionDuration >= minExecutionDuration);

I cannot submit the code for network reasons.
