Fixed – System.InvalidOperationException: Message size exceeded when attempting to send response to sandbox. Message Size 123 Mb. Max Allowed 128974848 Mb (Dataverse / Dynamics 365 )

Recently we got the below exception for one of our plugins
Message: System.InvalidOperationException: Message size exceeded when attempting to send response to sandbox. Message Size 123 Mb. Max Allowed 128974848 Mb.

Below is the code where we were getting the error. We were retrieving the notes records associated with the inspection response/inspection attachments. (Dynamics 365 Field Service)

And if we had a total of all attachments to it more than 100 mb it was failing.

Below is the test Work Order Service Task record for which we were getting the error.

There were a couple of other attachments also to it making a total of more than 100 Mb.

Here to fix the error instead of fetching all the note details at once and then processing the notes attachments, we updated our logic to process the notes attachments one by one.

Hope it helps..

How to – Create an Automated low-code plug-in (Dataverse) (experimental)

In the previous post, where we installed the Dataverse Accelerator app and saw how to write basic low-code Instant Plugins.

How to – Create an Instant low-code plug-in (Dataverse) (experimental)

Here we’d look at the Automated low-code Plugins.

Select the New Plugin option in the Dataverse Accelerator app to create Automate Plugins.

We get the option to select the table, the event, define the behavior of the plugin using Power FX, specify pre or post-operation, and the solution as shown below.

To keep it simple, we have created a plugin on pre-operation that checks for null, the email address field in the Contact record on Create, and if blank throws an error.

On trying to create a contact record without an email address, we get the exception as specified in the plugin.

That’s all we are done with our plugin.

Now interestingly if we check our solution specified, we will not find our plugin there. We need to add them to the solution manually right now, here we need to look for FxExpression.

And all the details here

Hope it helps..

ParentContext property of IPluginExecutionContext – Dynamics 365 / Dataverse

Recently we had to write a plugin that should trigger only when a user has manually associated the record from the form (N-N relationship). This was because we were also doing the same association through another plugin, in which case we didn’t want this new plugin to trigger.

Here we can make use of ParentContext property to identify if the plugin is getting triggered because of another plugin.

Below we can see ParentContext property getting populated and also in the InitiatingUserId property we get the id of the user who triggered the plugin.

And if the user has manually performed the association from the form, we can see ParentContext being null.

Hope it helps..

How to – Use Plugin on Pre-Validation Stage in Dynamics 365 CE

Recently we had a requirement to delete the Account record without deleting the associated Contact records.

If we try deleting the account record we’d get the following message box

The relationship definition can’t be updated as well to achieve this

So, we wrote a plugin on the pre-validation stage of pre-delete event of Account, which will retrieve and loop through all the child contact records and set its parent customer field as null.

In case of pre-operation the child records were not available.

</p>
<p>public void Execute(IServiceProvider serviceProvider)<br />
{<br />
ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));<br />
IPluginExecutionContext pluginContext = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));<br />
IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));<br />
IOrganizationService organizationService = serviceFactory.CreateOrganizationService(pluginContext.UserId);<br />
EntityReference targetEntity = (EntityReference)pluginContext.InputParameters["Target"];<br />
QueryExpression getContacts = new QueryExpression("contact");<br />
getContacts.Criteria.AddCondition(new ConditionExpression("parentcustomerid", ConditionOperator.Equal, targetEntity.Id));EntityCollection allContacts = organizationService.RetrieveMultiple(getContacts);foreach (Entity contact in allContacts.Entities)<br />
{<br />
Entity contactToBeUpdated = new Entity("contact");<br />
contactToBeUpdated.Id = contact.Id;<br />
contactToBeUpdated.Attributes["parentcustomerid"] = null;<br />
organizationService.Update(contactToBeUpdated);<br />
}}<br />

Another practical scenario

Unit Test RetrieveAttributeResponse in CRM using Microsoft Fakes.

Hi,

Recently we wrote a plugin that was using RetrieveAttribute class to get the label as well as value of the optionset field.

The issue that we faced over here is that the AttributeMetadata property of RetrieveAttributeResponse is read only, we cannot set it. The following post provided the solution i.e. writing a wrapper class over the RetrieveAttributeResponse

http://www.alexanderdevelopment.net/post/2013/01/13/How-to-unit-test-C-Dynamics-CRM-interface-code-part-III


organizationService.ExecuteOrganizationRequest = request =>
 {
 var retrievedPicklistAttributeMetadata = new PicklistAttributeMetadata();

if (request.Parameters["LogicalName"].ToString() == "lss_service_request_status")
 {
 var optionMetadata = new OptionMetadata(new Label("Closed", 1033), 10);
 optionMetadata.Label.UserLocalizedLabel = new LocalizedLabel("Closed", 1033);
 optionMetadata.Label.UserLocalizedLabel.Label = "Closed";

var serviceRequestTypeOptionSet = new OptionSetMetadata
 {
 Name = "lss_service_request_status",
 DisplayName = new Label("Service Request Status", 1033),
 IsGlobal = false,
 OptionSetType = OptionSetType.Picklist,
 Options = { optionMetadata }
 };

retrievedPicklistAttributeMetadata.OptionSet = serviceRequestTypeOptionSet;
 }

var retrAttResponse = new RetrieveAttributeResponseWrapper(new RetrieveAttributeResponse());
 retrAttResponse.AttributeMetadata = retrievedPicklistAttributeMetadata;
 return retrAttResponse;
 };

Hope it helps!
