Passing timefield as a panel link parameter

Hello guys,

I’m using Grafana version 5.0.3 and I have an issue with panel links. When I try to pass the time field value (epoch_millis) as a parameter in the link url using the $__cell_n predefined variables, it’s interpolated as a multi-value variable (i.e, enclosed with curly braces). Is this the expected behavior?

Thanks in advance,

what is the value for that cell? is it an array?
