NewFormFieldSelect cannot be retrieved by request.Payload.StringSlice in octant 0.21.0

What steps did you take and what happened:
I want to upgrade antrea-octant-plugin by using the latest 0.21.0 octant plugin API. However, I met an issue in the latest 0.21.0 octant but the same code can work in octant 0.16.1.

I used component.NewFormFieldSelect for desTypeCol which is defined here https://github.com/antrea-io/antrea/blob/main/plugins/octant/cmd/antrea-octant-plugin/traceflow.go#L635. Now when I use
request.Payload.StringSlice(dstTypeCol), it returns the error that shows payload does not contain this field.

I did not meet this issue in previous 0.16.1 release, so I would like to know if there is any change in recent releases for this part which may cause this issue? Is there anything that my plugin needs to update?
Thanks a lot for your information!

What did you expect to happen:
request.Payload.StringSlice() can get the value defined in component.NewFormFieldSelect()

Anything else you would like to add:
Found some warning logs like below:
