Question mark in people layout

[frankdarwin]

In various People layouts, I see only question marks instead of faces. Sometimes these are replaced by faces after scrolling, sometimes not.
What is the reason for this ?

This symbol indicates that IMatch does not have a face for the person in that image.
This is normal if you link persons to faces - because there is no face in this case.

If you get this for images which have a normal face annotation, there might be a problem in the app or something else.
With only a screen shot of the effect I cannot tell much.

You need to provide more info, which IMatch version you use (there was a bug fix for this in one of the recent updates), if there are any errors or warnings in the log file, if the database diagnosis runs clean, if you have step to reproduce this (and which allow me to reproduced this here) etc.

I don't see any related reports in the official bug report board so this might be something that happens only on your computer and with your images and workflow.
Which makes this even harder to analyze without detailed info or step-by-step instructions which cause this.

I see the same. After using Face Manager to confirm faces...i see a loot of persons with a questionmark in people view. Must select a person and press F5 a couple of times to refresh, and then all people appear with faces again.

The app displays a question mark when it cannot fetch a face thumbnail.
If this happens on your machine, something is wrong. May be a yet unidentified bug or maybe some external influence.

We need to make this reproducible, e.g. by running the face manager in your web browser with the developer tools enabled so we can see in the network tab if the app receives error messages from IMWS when trying to load the faces. To do this, you need to

a) Identify a person that produces this problem.

b) Use the {File.Persons.OID} variable in VarToy App to get the person's unique OID

c) Launch the Face Manager in your web browser via this URL

http://127.0.0.1:50519/imatch/apps/FEATURES/people/face-manager/index.html?scope=%7B%22id%22:16%7D

Replace the red 16 with the OID of your test person.
This will open the FM in your browser for that person.
Do you see ? face tiles here as well?

If so, press <F12> to enable the developer tools.
Switch to the "Network"t tab
Press <F5> to reload the face manager.

If you see lines in red, make a screen shot and attach to a reply (you can trim the actual faces for privacy reasons.

Repeat these two steps, this time keeping the "Console" tab in the developer tools open.

Make sure you are using the latest IMatch 2021 version.
