when I updated `aws-api-gateway-client` from 0.2.17 to version 0.3.3 my Requests failed with status code 403 however it was working well before updating

export function apiRequest(options, cred, result, error) {
  var apigClientFactory = require("aws-api-gateway-client").default;
  var apigClient = apigClientFactory.newClient({
    invokeUrl: BASE_URL, // REQUIRED
    region: "us-east-1", // REQUIRED: The region where the API is deployed.
    accessKey: cred.accessKeyId, // REQUIRED
    secretKey: cred.secretAccessKey, // REQUIRED
    sessionToken: cred.sessionToken, // OPTIONAL: If you are using temporary credentials
    systemClockOffset: 0, // OPTIONAL: An offset value in milliseconds to apply to signing time
    retries: 2, //           function. Uses axios-retry plugin. Default is no delay.
    retryDelay: "exponential"
  });
  var pathParams = {};
  // Template syntax follows url-template https://www.npmjs.com/package/url-template
  var method = "POST";
  var additionalParams = {
    //If there are query parameters or headers that need to be sent with the request you can add them here
    headers: {
      "Content-Type": "application/json"
    },
    queryParams: {}
  };
  console.log("api client", apigClient);
  apigClient
    .invokeApi(
      pathParams,
      `/default/${options.pathTemplate}`,
      method,
      additionalParams,
      options.body
    )
    .then(response => {
      //This is where you would put a success callback
      console.log(`${options.pathTemplate} invoke api result`, response);
      result(response);
    })
    .catch(err => {
      //This is where you would put an error callback
      console.log(`${options.pathTemplate} invoke api error`, err);
      error(err);
    });
}

Hi,

I have the same issue after updating to version 0.3.3. Initially I reverted to 0.2.17, where the identical code worked again.

After reading @AhmedMesawer post, I tested again with v 0.3.3. First without changing any code, same issue. Symptom is a Content-Length: 0 in the request.

After commenting out the retries everything works as expected.

var apigClient = apigClientFactory.newClient({
    invokeUrl: config.api.invokeUrl,
    ...
    region: config.api.region,
    systemClockOffset: 0, // OPTIONAL
    //retries: 4,         // OPTIONAL
    retryCondition: (err) => { // 
        return err.response && err.response.status === 500;
    }
});

Looks like this is the source of the bug.

@AhmedMesawer I run into the same problem with 0.3.3. Switching headers to lower case helped me. Try “content-type”.
