Entity Search hangs with "Processing..." for Aderant Expert connector and adapter

I have rebooted both the app and IIS server numerous times and the problem remains.

I have performed database index rebuilds and the problem remains.

Hey Adrian,

Are you able to check the debugger in Internet Explorer to see whether the REST call to the broker service is returning anything? If possible, a network trace would also help if it is returning data.

*.har file coming...

Attribute in web.config was: maxQueryStringLength.  Previous value 16384, works now set to 32768.

Tried same solution on the IIS web server, but a different error appears:

Tried this solution from Matt: https://blog.jonschneider.com/2016/01/configuring-aspnet-applications-in-iis.html but unfortunately neither the web.config change nor the registry edit helped.

At this stage I have a working fix for the built-in server, but not for IIS.

(I rebooted the server after making the registry change, in case)

The request in Dev Tools in IE doesn't show the query parameters, and the request doesn't appear in the IIS log file:

Dev Tools in IE doesn't show the request parameters for a successful Search Entries request either, though.  This is for the Chris21 adapter that is displaying correctly:

Hi Engineering Group, could you please re-open this ticket.  The fix did not work for the IIS-based UI, as described above.  This problem is still happening and I don't have a fix for it.

Thanks.

Hi Adrian,

What other strategies have been attempted to resolve this issue? As the article above mentions, this is a restriction in the Http.sys process in windows (before the request even makes it to IIS). Microsoft documentation outlines making registry changes to resolve this ( https://support.microsoft.com/en-us/help/820129/http-sys-registry-settings-for-windows ), so further investigation is needed as to why the registry change did not resolve the problem.

As a first step, please try ensuring the value you enter for the registry change is within the range of valid values for the entry (the screenshot you've linked above is not within the range). See the Microsoft Support page for more information:

Hi Matt, everything relevant that I've done is documented in this task.  I will try setting it the registry setting to 65534, re-test and advise the outcome.  Thank you for the advice.

Hi Adrian,

Have you had any luck re-testing this with the updated registry value?

Not yet... I have to wait until I work on their system again.  They're in a change freeze, and also I am not allocated to work on this customer at the moment.
