[SOLVED] API Gateway Lambda request authorizer error when request has body

API Gateway Lambda request authorizer error when request has body

I am experiencing a weird issue with my Lambda request authorizer for this API gateway endpoint where when the request has a body, I get this error:

{
  "errorType": "UnprocessableEntityError",
  "errorMessage": "Invalid or malformed JSON was provided",
  "trace": [
    "UnprocessableEntityError: Invalid or malformed JSON was provided",
    "    at Object.createError (/var/task/node_modules/@middy/util/index.cjs:212:12)",
    "    at httpJsonBodyParserMiddlewareBefore (/var/task/node_modules/@middy/http-json-body-parser/index.cjs:25:42)",
    "    at runMiddlewares (/var/task/node_modules/@middy/core/index.cjs:123:27)",
    "    at runRequest (/var/task/node_modules/@middy/core/index.cjs:83:15)",
    "    at Runtime.middy1 [as handler] (/var/task/node_modules/@middy/core/index.cjs:37:16)",
    "    at Runtime.handleOnceNonStreaming (/var/runtime/Runtime.js:73:25)"
  ]
}

If I remove the body from the request, the authorizer works correctly, but of course the endpoint does not function as expected because there is no data passed to it. Conversely, if I remove the authorizer the request works as expected but is not protected by an authorizer.

The authorizer has a Payload Format Version of 2.0, and a Response Format of Simple.

The request body I'm trying to send is a simple 3 key-value JSON object like:

{
   "key1": "value1",
   "key2": "value2",
   "key3": "value3"
}

The authorizer configuration 512 MB memory and storage with a 30 second timeout.

Does anyone know how I might be able to allow for my request to have a body, but the authorizer not throw this error?

Solution

I have solved the issue. I removed middyfy from the export in the function and that solved things. I guess middy should not be used for authorizers.
