GuidSerializer cannot serialize a Guid when GuidRepresentation is Unspecified" indicates that the MongoDB C# driver is encountering a GUID (Globally Unique Identifier) that does not have a specified representation during serialization.
This typically happens when the driver needs to know how to store the GUID in MongoDB, but the default or configured GuidRepresentation is Unspecified.
Resolution Steps:
BsonSerializer.RegisterSerializer(new GuidSerializer(GuidRepresentation.Standard));
if (customer.CustomerGuid== Guid.Empty)
{
customer.CustomerGuid = Guid.NewGuid();
}
customer.CustomerGuid = Guid.NewGuid();
await this._customerService.UpdateCustomerAsync(customer);
