Error retrieving a secret value from secrets manager

Question

I'm trying to retrieve a secret value from secrets manager using an API client via a post request.

I keep getting the following error in the response:

{
    "Output": {
        "__type": "com.amazon.coral.service#SerializationException"
    },
    "Version": "1.0"
}

Answer

My guess is that this appears to be a malformed API request parameter. It seems that many others have had similar issues. Please refer to the following URL.

Answer

OK, thanks, tried a couple of different things. Now I'm getting an "UnknownOperationException":

{
    "Output": {
        "__type": "com.amazon.coral.service#UnknownOperationException"
    },
    "Version": "1.0"
}

Answer

Figured it out. There was a syntax error in the request body JSON.

Answer

Is your secret value is JSON? if yes, please see if it is a valid jSON.
SerializationException can occur if there is a missing comma, curly braces etc.
