CRM Plugins Error - An item with the same key has already been added

Posted on by Community Member

Hi,

In our Opportunity Update Post-Operation Synchronous plugin, we got the following error:

An item with the same key has already been added

Here's the stack trace:

at Microsoft.Crm.Extensibility.OrganizationSdkServiceInternal.Update(Entity entity, CorrelationToken correlationToken, CallerOriginToken callerOriginToken, WebServiceType serviceType, Boolean checkAdminMode) at Microsoft.Crm.Extensibility.InprocessServiceProxy.UpdateCore(Entity entity) at CRMPlugIns.Opportunity.Opportunity_Update_Post.ExecuteLogic()

I don't understand how this is possible since I don't use the entity.Attributes.Add(key, value) method. I simply set the value of an attribute like this: entity["attributeName"] = attribute value.

Any ideas?

Thank you!

It should not be doing it with entity["attributeName"] syntax, but, maybe, there is another plugin involved?

Can you debug the plugin and the specific method? If so you best beat is to input a break point right before the error happens in your code. You might also want to add a try catch around your block of code to get even more details.

Hi,

Anatoliy

Please provide the complete code you have used as it seems like the error is coming from any other part of the plugin.

Also, I suggest you to enable the traces in the plugin in order to get the exact location of the cause of the error.

Thank you,

Alex: it's possible. Altough, I haven't seen this error occur for the past 2 weeks. I'm starting to think the code changes we made recently to refactor the plugin fixed the issue.

James: I can't debug the plugin unless I create a console project to emulate an entity being updated. Glad you asked this question. We really should start thinking about setting up mock tests for all our Plugin methods.

Jeet: Good idea. I think we will enable traces when we see this error happening consistently. It's been 2 weeks since I last saw this error.

Thank you all for your response. Some very good ideas came out of this!

Hi,

Please check duplicate detection rules enabled for the entity as well.tlThere can be a rule being applied for the field.

Hope this helps:)

Hi Jeet - Thanks for the reminder!

I asked this same question on the CRMUG forums and got a response worth sharing. Please see below:

entity.Attributes.Add(key, value) is equivalent to entity[key] = value; Use the SetAttributeValue msdn.microsoft.com/.../microsoft.xrm.sdk.entity.setattributevalue.aspx

Here's a combined list of possible solutions:

Use entity.SetAttributeValue method for safe attribute setting https://msdn.microsoft.com/en-us/library/microsoft.xrm.sdk.entity.setattributevalue.aspx

Debug plugin using plugin profiler: https://msdn.microsoft.com/en-us/library/gg328574.aspx

Enable tracing in the plugin to get the exact location of the cause of error

Check duplicate detection rules

I will mark this answer as the suggested answer so that it's easily visible to individuals with a similar error. Let me know if any of you have a problem with this decision.

Thank you.

You can also do before assigning the key you can check below

if ( !PluginExecutionContext.SharedVariables.Contains("keyname")){

// then assign key

PluginExecutionContext.SharedVariables.Add("keyname", "XXXXXX");

}
