"Data Source Not Found" in -- Mixed -- for zabbix datasource assigned by variable

[carlosmaor]

Describe the bug
Good day. I get the error "Data source not found" when selecting -- Mixed -- data source in a panel and assigning Zabbix through a variable. It appears that the UID of the selected datasource is not being correctly obtained.

logger=datasources t=2024-07-11T10:17:39.685450353Z level=warn msg="Invalid datasource uid. A valid uid is a combination of a-z, A-Z, 0-9 (alphanumeric), - (dash) and _ (underscore) characters, maximum length 40. Invalid characters will be replaced by dashes." uid=${ds_test} action=read name= error="invalid UID"

This behavior only occurs when using variables referencing the Zabbix datasource. It has been tested across multiple versions of Grafana using grafana-zabbix 4.5.2.

The issue can be replicated on Play Grafana-Zabbix.
