Heya,

I have started to get this error when updating contact.

it occurs alternately...

The only change I have made was to update the pre update plugin with some logic which encrypt a string using AES encryption.

Also, at the bottom of the trace log its says:

[Microsoft.Crm.Audit: Microsoft.Crm.AuditCreateUpdatePlugin]
[3f98ba77-2929-4e32-8d9d-70c82ec929bc: AuditCreateUpdatePlugin]

Any ideas whats that error means?

Thanks!

Can you please provide the full details of the error? This portion of the trace does not give us the exception message.

I have disabled all the Audits yet it still occurs

Also, I could isolate method which probably causing this error:

public static string DecryptStringFromBytesByAes(byte[] cipherText, byte[] Key, byte[] IV)
{
if (cipherText == null || cipherText.Length <= 0)
throw new ArgumentNullException("cipherText");
if (Key == null || Key.Length <= 0)
throw new ArgumentNullException("Key");
if (IV == null || IV.Length <= 0)
throw new ArgumentNullException("IV");

string plaintext = null;

using (Aes aesAlg = Aes.Create())
{
aesAlg.Key = Key;
aesAlg.IV = IV;

ICryptoTransform decryptor = aesAlg.CreateDecryptor(aesAlg.Key, aesAlg.IV);

using (MemoryStream msDecrypt = new MemoryStream(cipherText))
{
using (CryptoStream csDecrypt = new CryptoStream(msDecrypt, decryptor, CryptoStreamMode.Read))
{
using (StreamReader srDecrypt = new StreamReader(csDecrypt))
{

plaintext = srDecrypt.ReadToEnd();
}
}
}

}

return plaintext;
}

Hi Dear,

I was facing same issue while working on update plugin. This has been fixed for me. I was updating entity object in plugin which was registered on Pre-Operation which is not right. So if you are doing such kind of thing then you gonna face such issue.

Check your plugin code i don't think its from CRM side. Its our blunder which is causing this error.

Cheers!

In the plugin execution pipeline, pre-validation does happen within the database transaction. The begin transaction should only happen after this stage. It looks like somehow some custom code is trying to perform an operation that requires a lock on the record but the lock cannot be acquired at that point and it's too early for that at that point.

In simple terms, a Create/Update/Delete operation is most likely being performed in a Pre-validation stage.

Please see the following if you would like to read more about the execution pipeline
