Please find the config in /etc/aziot/config.toml file

trust_bundle_cert = "file:///home/azureuser/cert/certs/azure-iot-test-only.root.ca.cert.pem"
[edge_ca]
cert = "file:///home/azureuser/cert/certs/iot-edge-device-ca-test-device-ca-certs-full-chain.cert.pem"           
pk = "file:///home/azureuser/cert/certs/iot-edge-device-ca-test-device-ca-certs.cert.pem" 

[provisioning]
source = "manual"
connection_string ="HostName=XXXXXXXXX-dev.azure-devices.net;DeviceId=test-device;SharedAccessKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXX"

Solution

I made a mistake while mentioning the path to the root ca. The issue is resolved
