### Affected Services [**REQUIRED**]
<!-- Can you pin-point one or more EdgeX services (Data, Metadata, Command, etc...) as the source of the bug? -->
<!-- ✍️edit: --> The issue is located in: device-modbus


### Is this a regression?

<!-- Did this behavior work correctly in the previous version? -->
<!-- ✍️--> Yes

### Description and Minimal Reproduction [**REQUIRED**]
1. Deploy EdgeX by attached compose file
[docker-compose-no-secty.yml.zip](https://github.com/edgexfoundry/device-modbus-go/files/11035968/docker-compose-no-secty.yml.zip)

2. device-modbus create default profiles and devices with autoevent
3. Found error on device-modbus logs

## 🔥 Exception or Error
