Could not compute value for ComputedIndexField - Service Host URI is not a Valid URI

Question

We have a sitecore 9.1.1 CM instance configured to use Azure Cloud. We have the relevant configurations enabled & disabled for each instance.

However we are seeing the following:

16784 22:55:11 WARN  Could not compute value for ComputedIndexField: potential for indexable: sitecore://master/{3FF23DB1-A0F7-46DF-84D3-E17FCC19CB06}?lang=ar-AE&ver=2

I know the computed index is defined by configuration for sitecore_suggested_text_index. The easiest option is to disable the fields but not really a fan of turning things off because they aren't working.

I'd like to know if we are missing something or if we do turn it off what is the potential setback of turning off fields potential, impact and recommendation?

Also can confirm that the azure search connection string is correct.

These errors can be caused if sitecore content testing has been disabled, you can verify this in the App_Config\Sitecore\ContentTesting\Sitecore.ContentTesting.config file:

<setting name="ContentTesting.AutomaticContentTesting.Enabled" value="false" />

Content tests let you test alternative variants of your website’s content to find out which pages, components, or combinations of components are the most effective with visitors. The content or components that you are comparing in a test should be designed to achieve the same goal.

You can take a look at the sitecore content testing glossary documentation https://doc.sitecore.com/users/93/sitecore-experience-platform/en/experience-optimization-and-content-testing-glossary.html

If you don't use this feature in your sitecore setup then the three fields must also be removed through a patch config file:
