MySQL Table Details dashboard showing No Data

[GenLN]

Description

Dashboard showing no data. Hundreds of clients connected to PMM server.
Variable "Service Name" not loading any value.
Query used for service_name variable is
label_values(mysql_info_schema_table_version, service_name)

This raw metric also crash victoriametrics when used in explore.
Only queries using "by" works.. for example:
label_values(max by(service_name)(mysql_info_schema_table_version), service_name)

Maybe solution is to use some kind of aggregation on the query or simple change metric to "mysql_up" and it should look like:
label_values(mysql_up, service_name)

Expected Results

Showing data per service name

Actual Results

No data, empty var Service Name

Version

PMM Server 2.34 > PMM client 2.34
