Could not fetch frame data from the server

I am using a share mount and I get this error when I scroll through the task.

I have tried this python script solution #3119 It didn't fix it - my error might be slightly different.
I have also docker compose down (2 days ago), git clone cvat, docker compose CVAT_Host=xxxxxxxx (does this give me the latest cat version or the development version? The same error still shows.

@davodogster Hello,
Make sure you are actually using the latest CVAT, have you run docker-compose pull to update your local images, or have you built them yourself?

Also, please attach logs from the browser and cvat container

The CVAT update guide doesn't say to use docker-compose pull. I've never come across that command before.

Here is the console for the browser error:

Docker logs cvat:

@azhavoro Hi Andrey. The CVAT update guide doesn't say to use docker-compose pull. I've never come across that command before.
https://openvinotoolkit.github.io/cvat/docs/faq/

When I update cvat I do:
docker-compose stop
delete old cvat folder
git clone cvat
create docker-compose.override file
docker compose up -d

When is docker-compose pull supposed to be run, and will I lose all of my docker volumes containing all of images image tasks and annotations if I use this command?

Cheers, Sam

@davodogster Hi Sam, the update guide needs to be updated a bit, docker-compose pull does not delete any associated volumes, it just updates your local images for the services that are defined in the docker-compose config from DockerHub if possible. Another way is to build the cvat images locally using docker-compose -f docker-compose.yml -f docker-compose.dev.yml build command.

@azhavoro Thanks a lot! It worked a charm and now I can export project as a dataset and the issue from above is solved.
