Unexpected Error thrown - 'Could not find Controller'

Unexpected Error thrown - 'Could not find Controller'

Symptoms:

When we attempt to navigate to pages in the Web UI directly - entering the URL manually into the address bar, for example:

<FNMS URL>/Suite/datainputs

We see a red bar Unexpected Error thrown, and are not able to access the Data Inputs page.

Diagnosis:

In our WebUI.log (ProgramData\Flexera Software\Compliance\Logging\WebUI\webui.log ), we see the following:

"An unexpected error occurred (the error ID from our Unexpected Error page)

System.Collections.Generic.KeyNotFoundException: Could not find controller 'datainputs'"

The error ID should match our 'We have a problem' page here, and occur each time we attempt to follow this URL - note the timestamp within our WebUI.log

[ERROR Timestamp  6437ms UnhandledErrors                        ] An unexpected error occurred (Error ID)

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Collections.Generic.KeyNotFoundException: Could not find controller 'datainputs'

Solution:

The URLs for the FNMS Web UI are case-sensitive.

While a 'DataInputs' controller exists, a 'dataInputs' controller does not.

Ensure that, if you are copying links from the FNMS web UI, your character case matches the URL generated by following the Data Inputs button within the Web UI's Settings button, for example.

For our example, note that the controller is 'DataInputs' (#Index_InventoryData isn't required to navigate directly to the page here)
