Good afternoon savcuoglu,
Sorry for the issues you are going through.
My initial piece of advice will be to check your Greengrass Core Device policy, and make sure it allows subscribing, sending and/or receiving to/from shadow topics. Policy should include something like:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"iot:Subscribe"
],
"Resource": [
"arn:aws:iot:region:account:topicfilter/$aws/things/thingName/shadow/name/applications-shadow/update/accepted"
]
},
{
"Effect": "Allow",
"Action": [
"iot:Receive"
],
"Resource": [
"arn:aws:iot:region:account:topic/$aws/things/thingName/shadow/name/applications-shadow/update/accepted"
]
}
]
}
You can always refer to documentation here, to tailor your policy to the corresponding shadow topic you are willing to track.
