Hi everyone,

Im trying to write the post images value of a field to another field once contact record is updated.

I get the following error

Unexpected exception from plug-in (Execute): ClassLibrary1.Class1: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. 

Below is my code 

ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
Entity entity = (Entity)context.InputParameters["Target"];



string pretopic = string.Empty; string posttopic = string.Empty;

if (context.PreEntityImages.Contains("LeadTopicImage") && context.PreEntityImages["LeadTopicImage"] is Entity)
{

Entity preMessageImage = (Entity)context.PreEntityImages["LeadTopicImage"];
pretopic = (String)preMessageImage.Attributes["jobtitle"];

}
if (context.PostEntityImages.Contains("LeadTopicImage") && context.PostEntityImages["LeadTopicImage"] is Entity)

{

Entity postMessageImage = (Entity)context.PostEntityImages["LeadTopicImage"];
posttopic = (String)postMessageImage.Attributes["jobtitle"];

}

context.InputParameters.Contains("spousesname");
entity.Attributes.Add("spousesname",posttopic);

    Hi Jonathan,

    I understand that you wrote in the beginning to validate the entity from the context input parameter( context.InputParameters.Contains("Target") ) , that is correct .

    I can see again you are checking the the attributes in the context input parameter , you can not check attributes in the input parameter like below . If you are looking for attributes you should do the contains in the entity /entityreference type only instead of input parameter.

    context.InputParameters.Contains("spousesname");

    Now question is in which entity spousesname attributes exists ?

    If the attributes in the same entity , you can simply get the  entity and set the entity value like below- 

    Entity record = (Entity)context.InputParameters["Target"]; // I believe you have already got the entity in the above lines
record["attributename"] = /* any value */;


    If the spousesname  attributes belongs to another entity you need to create the entity separately,

    Entity account = new Entity("EnityName"); // Replace EntityName

account["spousesname"] = "Sample text";

    Hope this helps.

    Hi,

    Do you have registered pre image step and its name matching with above(i.e. preMessageImage - its case sensitive). if yes, Did You selected Jontitle in preimage step? 

    Please check, that should solve your issue.

    Hello,

    It is safer to use GetAttributeValue instead of referencing attribute directly because if there is no such attribute in your entity - you will get KeyNotFound Exception so instead of

    pretopic = (String)preMessageImage.Attributes["jobtitle"];

    use

    pretopic = preMessageImage.GetAttributeValue<string>("jobtitle");

    the same for the posttopic.

    Also what does

    context.InputParameters.Contains("spousesname");

    this line mean?
