Sitecore Coveo Search Resource Component and Dictionary Items

/ Parag Daraji / Leave a comment

Recently, I am working on a bug reported by one of our tester. The issue stating none of the Coveo pages on few of the SXA websites working post upgrade of Coveo SXA module.

The Issue

The website suddenly started showing error message “The component is not available at this moment. Please contact the site administrator.” under Coveo’s Search Resources Component on the website pages.

Strangely, the same functionality(or rather I say partial design) used by other SXA website are working like charm. But only 2 websites which has whole Coveo Search functionality has been broken.

The Finding

First obvious thing I did was open the Google and search for the error message. After some time spending on reading multiple blogs and articles, I come with this link on Coveo’s articles.

As Article suggested, I have verified both the conditions, firstly checked extranet/Anonymous(user and domain configure with Site Definition) has read access to both Sitecore/System/Dictionary items and additional dictionary item configured at the Coveo Search Resource Data source item. Secondly, checked we have correct dictionary item selected under the field Additional Dictionaries for Coveo Search Resources item configured as data source to respected UI component.

Now, I was trying to isolate the issue, to make sure the issue is due to either dictionary or its child items. So, I tried to remove the dictionary item form the additional dictionary field, publish the item and magically all the broken Coveo Pages started working…!!!

So now, I am sure there is something to do with the dictionary item for that SXA website.

The Solution

I started decoding the Coveo Search Resources SXA UI component and found the logic for getting the component properties have a validation which validates the unique dictionary keys under the selected dictionary.

This is a great lead…..!!!(it took me fair few hours of dotPeeking to find this out) That left me with great confidence that there are some dictionary entry item which has the duplicate value in the Field Key.

I did first obvious check of unique item name by turning validation rule on via Sitecore’s Content Editor’s left gutter.

But none of the dictionary entry items have duplicate name. So now, I need to relay on my Poweshell skills to find the duplicate value on Key field of item /sitecore/templates/System/Dictionary/Dictionary entry.

I did created and executed the script to find the duplicate value in the field and found there is one entry under the dictionary which has exact same value present in the Key Field.

I removed that unwanted entry item which is lately added by one of the content editor while copying dictionary entries from older SXA website to the new one.

Happy Coveo Sitecore search…!!!

Sitecore Docker -Coveo Diagnosis Page Search Rest Endpoint Issue

/ Parag Daraji / Leave a comment

While configuring Coveo search on my local development environment using Docker, something got my attention on Coveo’s diagnosis page(<<Sitecore CM Host>>/sitecore modules/Web/Coveo/Admin/CoveoDiagnosticPage.aspx).

This page has all the green ticks except for the one. This is Coveo Search REST Endpoint. See image below for more details.

Coveo Diagnostic Page REST API Error
Coveo Diagnostic Page REST API Error on Docker

As usually, I copied the API end point URL and hit in the Browser and it serve the request with no error. It is HTTP-200 response with valid JSON result.

The error in the log file also not giving any lead either.

Coveo.SearchProvider.Applications.BaseVerifier.VerifyComponent(:0) ERROR StateVerifier has encountered an error while verifying the component "Coveo Search REST Endpoint".<br>Exception: Coveo.SearchProvider.Applications.StateVerifierException<br>Message: Failed to obtain resource located at 'http://sicore930.dev.local/coveo/rest/'. See inner exception for details.<br>Source: Coveo.SearchProvider.Applications<br>at Coveo.SearchProvider.Applications.CommonStateVerifier.TryPingRestEndpoint(String p_Endpoint)<br>at Coveo.SearchProvider.Applications.CommonStateVerifier.<>c__DisplayClass11_0.b__0()<br>at Coveo.SearchProvider.Applications.BaseVerifier.VerifyComponent(Func`1 p_VerifyMethod, String p_ComponentName)

I opened docker powershell command for the cm container and tried to request the host from within container.

PS> Docker container ls

Grab the name or container id

PS> Docker exec -it <<container name/id>> powershell

This will open a powershell window connected to the container specified.

PS> Invoke-RestMethod -Uri "http://sitecore930.dev.local/coveo/rest" | ConvertTo-Json

It has given me following error

Now things are little clear to me. The Coveo diagnosis page is using current host to make REST API request from IIS server running on the container. The container does not have host file entry to reseolve the host url.

So now, I started searching how to make entry in container’s host file??? I was sure, I am not the first person who wanted this kind of stuff.

Following command has does the trick. but for that we need to first fire up the command prompt of the cm container.



PS> Docker exec -it <<container name/id>> powershell

Once the CM’s command prompt is ready execute below command to add the host file entry.



C:> echo 127.0.0.1 sitecore930.dev.local >> "C:\Windows\System32\drivers\etc\hosts"

After executing above command on Container’s command prompt, now my Coveo Diagnosis page is Happy…!!!

Please do let me know, is there any better solution you guys have in place for this issue.

Till that time happy Coveo searching…!!!

Additional powershell command to check the content of the file:



PS> Get-Content -Path <<fully qualified file path>>
