I am using the standard blog tutorial on integrating api gateway with step functions from here: https://docs.aws.amazon.com/step-functions/latest/dg/tutorial-api-gateway.html
My step function expects the following output:
{
"my_params": {
"config": "config_value"
}
}
the Request body needed to do a post request as mentioned in the blog is:
{
"input": "{}",
"name": "MyExecution",
"stateMachineArn": "arn:aws:states:us-east-1:123456789012:stateMachine:HelloWorld"
}
I am passing my required input like this:
{
"input": {
"my_params": {
"config": "config_value"
}
},
"name": "MyExecution",
"stateMachineArn": "my-arn"
}
However, I am continuously getting following error:
{
"__type": "com.amazon.coral.service#SerializationException",
"Message": "Start of structure or map found where not expected."
}
Can someone tell me what exactly is the problem here? What am I doing wrong here? Quick help appreciated.
Use escape character for your parameters as follows
{
"input": "{
\"my_params\": {
\"config\": \"config_value\"
}
}",
"name": "MyExecution",
"stateMachineArn": "my-arn"
}
