MIM 2016 SP2 Portal Warning SP.Web.GetContextWebThemeData sharepoint Microsoft.ResourceManagement.PortalHealthSource Event 1

I've a sp 2019 on-prem with an upgrade installation of MIM 2016 SP2.

All is working well but each request or search in portal causes a warning log.

"The portal was unable to complete a request and showed a user the default error page.

 An unhandled exception was caught."


This is annoying but not a real problem.

Anyway looking for network call from browser I find:

http://mim/IdentityManagement/_api/SP.Web.GetContextWebThemeData?lcid=1033 http response 302

and then this call go (behind the scene) to Error page /_layouts/15/MSILM2/ErrorPage.aspx

In IIS Log:

GET /IdentityManagement/default.aspx - 443 http response 200

GET /_vti_bin/client.svc/SP.Web.GetContextWebThemeData lcid=1033 443 httpresponse 302

GET /_layouts/15/MSILM2/ErrorPage.aspx - 443 http response 200

In any case all page of portal are working properly.

My question is: why portal is calling this api async and log warning on portal?

How can be disabled this.

thank you.

Best regards.
