How to Increase JSON Maxlength

Posted on by Community Member

Hi,

When we track a long email ( like 10 replies in that email) in CRM 2013 on premises . The Activities in Social Pane will cause an error.

Error: System.InvalidOperationException: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

at System.Web.Script.Serialization.JavaScriptSerializer.Serialize(Object obj, StringBuilder output, SerializationFormat serializationFormat)

at Microsoft.Crm.Application.Platform.Grid.GridDataProviderBase.PrepareJsonSerializedGridData(StringBuilder sbData)

at Microsoft.Crm.Application.WebServices.AppGridWebServiceHandler.Refresh(String gridXml, StringBuilder sbXml, StringBuilder sbHtml, Boolean returnJsonData)

at Microsoft.Crm.Application.WebServices.AppGridWebServiceHandler.ProcessRequestInternal(HttpContext context)

When I delete those long emails, It works fine again. But I want to increase the MaxJsonlength to avoid this errors but It didnt work. I tried to go to web.config and increased maxJosnLength to 2gb but it's still getting errors. The default is 1gb.

<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="2147483647" />

</webServices>
</scripting>
</system.web.extensions>

Do I need to go anywhere else to change to make it happen ? I am appreciated all the comments.

Thank you very much,

<httpRuntime maxRequestLength="8192" />
<webServices>

<soapExtensionReflectorTypes>
<add type="Microsoft.Crm.Sdk.CrmServiceSoapExtensionReflector, Microsoft.Crm.WebServices" />
</soapExtensionReflectorTypes>

<remove name="BasicProfile1_1" />
</conformanceWarnings>
</webServices>

<configuration>

<system.web.extensions>

<scripting>

<webServices>

<jsonSerialization maxJsonLength="50000000"/>

</webServices>

</scripting>

</system.web.extensions>

</configuration>

However if you use an iframe with mvc

the MVC json serializer does not look at the webconfig to get the max length (thats for asp.net web services). you need to use your own serializer. you override ExecuteResult and supply you own json serializer. to override the input, create a new JsonValueProviderFactory, then override ValueProvider in the controller to return your new json factory when its a json request.

FYI this is supposed to be fixed in CRM2013 SP1 - here's the excerpt from the SP1 KB (support.microsoft.com/.../2941390)

• When attempting to load activities on the Social Pane in Microsoft Dynamics CRM 2013 that have large amounts of text in the description, users encounter the following error: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Fast forward a couple of years to 2016. We use Dynamics CRM Online (version 7.1.1.4466 currently) aka 2015 Update. Associated with our usage of embedded ClickDimensions, we have seen this error when editing a ClickDimensions draft email message.

I'm not familiar with the suggested fix - edit web.config. Is that fix only applicable to on-premises CRM instances or can it be done on CRM Online instances by a CRM developer?

thanks!
