SharePoint 2016 – SharePoint designer workflow – resolving error – Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file.) (0, 0) Activity ‘ID11’ validation failed: Property “Condition” has invalid value. Condition expression is invalid. The condition expression can not be null.)

Hi All,

Greetings for the day 🙂 LIFE IS BEAUTIFUL 🙂

Today new issue, and solution 🙂

Issue / Error – In SharePoint 2016, while publishing SharePoint Designer workflow getting following error

(-1, -1) Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration fType System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file.) (0, 0) Activity ‘ID11’ validation failed: Property “Condition” has invalid value. Condition expression is invalid. The condition expression can not be null.)

The error entry suggests that System.CodeDom.CodeBinaryOperatorExpression is not included in the authorized types

Details / Background :

• We have migrated our SharePoint 2013 site to SharePoint 2016
• We have few workflows as well which are migrated successfully
• Workflow is made at List level
• Workflow is assigning unique permission to folder on the given list item
• When we try execute the workflow we were getting an error – “Workflow canceled by System account“
• There is nothing in ULS and History list as well
• So thought to “Publish” the workflow again
• While publishing the workflow we get the above error

Environment:

• SharePoint 2016
• SharePoint 2013 designer workflows – migrated from SharePoint 2013 to SharePoint 2016

Cause :

Workflow Foundation (WF) runs workflows only when all dependent types and assemblies are authorized in the config file (or added explicitly through code) in the following tree:

<configuration>

<System.Workflow.ComponentModel.WorkflowCompiler>

<authorizedTypes>

<targetFx>

Solution :

• As per some blog posts we tried by activating “Workflow” feature but no luck 🙁
• As per some blog posts we cleared SharePoint Designer Cache but no luck 🙁
• Created new workflow on the same list but same issue
• After bit searching it found that issue is with web.config file. There are several entries for “Authorised Assemblies” are missing
• This is caused by the recent .Net security update on our box
• Symptoms : SharePoint out-of-the-box workflows stop working
• Following are the entries which we added in web.config file of our web application under the tree –

<configuration>

<System.Workflow.ComponentModel.WorkflowCompiler>

<authorizedTypes>

<targetFx>

 <authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeBinaryOperatorExpression" Authorized="True" />

<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodePrimitiveExpression" Authorized="True" />

<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeMethodInvokeExpression" Authorized="True" />

<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeMethodReferenceExpression" Authorized="True" />

<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeFieldReferenceExpression" Authorized="True" />

<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodeThisReferenceExpression" Authorized="True" />

<authorizedType Assembly="System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" NameSpace="System.CodeDom" TypeName="CodePropertyReferenceExpression" Authorized="True" />

After just adding these entries to web.config file of our web application we could published workflows successfully and running successfully 🙂

Please note – above entries are for the SharePoint 2013 and later versions. If you have SharePoint 2010 box then there are bit different entries

Thanks for reading 🙂 HAVE A GREAT TIME AHEAD 🙂
