I’m getting the below response in AWS Appsync console, when i try to invoke graphql API.
Request failed with status code 400
Query:
query MyQuery {
getUserData(inputArguments: $inputArguments) {
__typename
}
}
Variables:
{
"inputArguments": {
}
}
I’m unable to debug it as Lambda is not being invoked.

This is very likely caused by insufficient rights. Does Appsync have the rights to call the Lambda function?
Somawhat similar problem discussed here
https://github.com/aws/aws-cdk/issues/19239
Excerpt code from the linked issue that was the solution. It grants appsync.amazonaws.com rights to call the ‘authorizerLambda’ lambda:
authorizerLambda.addPermission("appsync", {
principal: new ServicePrincipal('appsync.amazonaws.com'),
action: 'lambda:InvokeFunction',
})
