Zabbix 5.4: method not found. Incorrect API "application"

Describe the bug I began rebuilding my Zabbix/Grafana monitoring again from scratch (I wanted to start over) using Docker containers. I had everything functional and suddenly Grafana won’t display some values on a Dashboard with error Incorrect API "application". I haven’t been able to narrow down exactly why some values will display and some wont. I went so far as to start over with Grafana in case I I’d caused the issue but a fresh installation of Grafana and the plugin result in the same issue.

Expected behavior Grafana should show all widgets.

Not sure if known, but I discovered a hack in Grafana to resurrect broken graphs. You edit your graph and then remove the content of “Application” field, leaving the item and the rest of them untouched, then it started to present graph. Discovered accidentialy because one of graphs had the application field empty and that one worked well after zbx 5.4.0 kicked in yesterday. Link to evidence.
