CRM Plugin - "The given key was not present in the dictionary."

Posted on by Community Member

Hi,

I'm trying to create a plugin which will take set an entity to a dynamic value based on the primary entity's Id. Essentially, when I create a new 'opportunity' entity, I want to update a text field containing a related url. I think this should be quite simple, and I can get this to work when creating a new 'opportunity', but for some reason running the workflow on an existing 'opportunity' gives the following error: "The given key was not present in the dictionary".

I have seen similar issues online, but nothing that quite solved this, can anyone help?

            IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
            IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
            OrganizationServiceContext ctx = new OrganizationServiceContext(service);

            Entity targetEntity = (Entity)context.InputParameters["Target"];     

            {
                //retrieve Record GUID
                Guid recordId = (Guid)context.PrimaryEntityId;

                //Set Field Value = url + recordId
                targetEntity["web_url"] = "https://website.com/" + recordId;
                service.Update(targetEntity);

            }

Hello,

It looks like your code is written for Custom workflow activity and not for plugin. Can you please provide your full code?

Hi ,

This message says that the property you have declared to update is not found in the target entity. Make sure your target enity contains the attributes web_url

Try with this -

IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>(); IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>(); IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId); OrganizationServiceContext ctx = new OrganizationServiceContext(service); Entity targetEntity = (Entity)context.InputParameters["Target"]; { //retrieve Record GUID Guid recordId = (Guid)context.PrimaryEntityId; //Set Field Value = url + recordId if (targetEntity.Attributes.Contains("web_url")) { targetEntity["web_url"] = "https://website.com/" + recordId; service.Update(targetEntity); } }

Goutam,

I'm really sorry but your reply doesn't make sense. targetEntity["web_url"] will throw an exception when code tries to get value and key is not there. When code sets the value no check is required.

I believe problem is in line

Entity targetEntity = (Entity)context.InputParameters["Target"];

because context is IWorkflowContext and not IPluginExecutionContext but I want to check full code first.

Andrew ,

My intention was to point out the issue based on the code shared here to troubleshoot . I believe you are aware that if the object don't have the attributes (web_url ) in the entity object and trying to execute the code targetEntity["web_url"] then this obvious that it will give error "The given key was not present in the dictionary". I believe this is C# error.

I agreed with you that here we need full code to make it work.

Thanks for your clarification .

I'm aware. Correct me if I'm wrong if code and explanations are correct

var record = new Entity();

record["fieldname"] = "test";//No exception - if there is fieldname it will be replaced with "test" value, if there is no - key "fieldname" will be added with "test" value.

var value = record["otherfieldname"];//Exception because otherfieldname is not present.

That's what I meant saying your change makes no sense.

Hi Andrew,

Correct me if I am wrong.

This is possible if you are using late bound entity type , but the code shared here in the post is an early bound entity type so there is no chances to replace the attributes name .

var record = new Entity();

record["fieldname"] = "test"; // This is correct for late bound entity type.

All the code in this post is late bound. Nobody provided any example of early bound. What you've told is correct - I answered your question. Now please tell me if my previous reply is correct or not.

Hi Andrew ,

I already answered that for late bound entity type your code is correct , but here in the below code targetentity has already filled with early bound entity type in the below code if I am not wrong.

Entity targetEntity = (Entity)context.InputParameters["Target"];

For early bound there should be some class mentioned other then "Entity" like

var target = (Account)context.InputParameters["Target"];

So for me it's still not clear - where did you see Early Bound?

My concern is what is the type of outcome "targetEntity " here below code if I consider as plugin perspective -it is early bound object right?

Entity targetEntity = (Entity)context.InputParameters["Target"];
