Fix unexpected error when approving requests in App Broker

Title

If an approver sees an unexpected error when approving a request on the Approve/Reject tab, the request can’t be approved.

Example:

This issue happens when the request includes special characters in notes, questions, or other text fields.

You may also see a website.log file exception that looks like this:

Unhandled Exception http://localhost/esd/RequestDetails.aspx?GUID=e0ab47e9-d7a4-4008-8956-ab3542c86422&Focus=general&Show=pending&PageSource=0+&RequestType=0+&PackageType=28&rwndrnd=0.035809017113591524 A potentially dangerous Request.Form value was detected from the client

Use the steps in this article to prevent IIS from validating request input by modifying the Web.config file.

Solution

Open the Web.config file on the App Broker server.
Location:

C:\Program Files (x86)\Flexera Software\App Portal\Web\Web.Config

Find the following section:

<location path="MyRequests.aspx">

<system.web>

<pages validateRequest="true" />

<httpRuntime requestValidationMode="2.0" />

</system.web>

</location>

Change validateRequest="true" to validateRequest="false".

<location path="MyRequests.aspx">

<system.web>

<pages validateRequest="false" />

<httpRuntime requestValidationMode="2.0" />

</system.web>

</location>

Run IISReset on the server to apply the change.
Reapprove the request.

TIP: Use plain text in the approve/reject comment box when approving requests.

Outcome

The request approval will complete without the unexpected error.
