invalid character '<' looking for beginning of value

[lim4k]

Hi,
our zabbix provider switch zabbix to HTTPS with cert, so i have updated grafana and zabbix plugin to latest versions

Grafana	Zabbix	Grafana-Zabbix Plugin
v7.3.2	4.0.5	4.0.1

after enable "Skip TLS Verify" i got only "invalid character '<' looking for beginning of value" on zabbix connection

logs

@lim4k check the API url.
in my case it looks like https://zabbix.host/api_jsonrpc.php
