----------------------------------------------------------------

Just for clarification, so this would work in the next release i.e. 3.20.4?
Or this should work in 3.20.2 as well?

I tried this as below but still not working:
{code:java}
from("plc4x:modbus-tcp://localhost:502?tag=value-1=holding-register:1"){code}
The tags attribute is still null.

*There is a requirement in my project that the endpoint should be String i.e. all the configurations should be in URI only and not as of type Endpoint.*

> I am using [ModbusPal|https://plc4x.apache.org/users/getting-started/virtual-modbus.html] to create the Virtual modbus.
> I am using the endpoint URI as:

> plc4x:modbus-tcp://localhost:502?unitId=1&dataType=holding-register&addresses=1{code}
> Following is the screenshot of Modbus holding registers:

> Here *tags* are null, so it might be that I am not configuring the endpoint correctly.
> So, I tried by configuring the endpoint by creating an instance of Plc4XEndpoint and then configuring the tags there, it works like:
> {code:java}
> Map<String, Object> map = new HashMap<>();
>             map.put("value-1", "holding-register:1");
>             
>             Plc4XEndpoint plc4xEndpoint = new Plc4XEndpoint("plc4x:modbus-tcp://localhost:502",
>                     getContext().getComponent("plc4x"));
>             plc4xEndpoint.setTags(map);
>             from(plc4xEndpoint).log("value : ${body}"); {code}
> But why it is not working if I configure the endpoint as just String?
> Note:
> I tried with below endpoint and it is also not working:
> {code:java}
> plc4x:modbus-tcp://localhost:502?tags={unitId=1&dataType=holding-register&addresses=1} {code}
