phpMyAdmin - Error

I’m having problems doing an import from phpmyadmin, previously it worked correctly.

It shows me the following error:
Warning: File upload error - unable to create a temporary file in Unknown on line 0.

This is my service inside docker-compose.yml:

     image: phpmyadmin/phpmyadmin
     container_name: phpmyadmin
       - "${DB_ADMIN_PORT}:80"
       PMA_HOST: database
       PMA_PORT: ${DB_PORT}
       UPLOAD_LIMIT: 1000000000
       - .env
       - app_network

Never use the latest image, always use a specific version tag. Phpmyadmin could be updated and your old parameters don’t work the same way. In this case it sounds like a PHP error when trying to create the temporary file before copying to the final location. Since it happens before any of the user code, it shows its on line 0. Check if the filesystem is writable and you have enough space to create the file.
