Admin 5 no longer supports custom icons for admin tabs. The fa-icon property should be removed from the adminTab configuration in your adapter's io-package.json.
If your adapter has an admin tab configuration with a fa-icon property, remove it:
"adminTab": {
"singleton": true,
"name": {
"en": "test-adapter",
"de": "test-adapter"
},
"link": "",
- "fa-icon": "info"
}As referenced in the ioBroker.admin issue comment, Admin 5 handles tab icons differently and adapters should no longer specify their own icons.
Your adapter will continue to work, but the fa-icon property will be ignored by Admin 5. Removing it ensures your adapter configuration is clean and follows current best practices.
