Has anyone seen this before and what are the common solutions? I was worried it had to do with laptop RAM based on the first line of error code, but there seems to be more. Any help would be greatly appeciated.

there have error message

I don't see in the repository "sequelize-typescript" and it has caused an error message in Visual Studio.

import {Sequelize} from 'sequelize-typescript';
import { config } from './config/config';

If the URL being passed to Jimp doesn't work (like the original URL provided with the started code), then the error described in the title of this issue is displayed. This is because Jimp.read throws an exception which should be rejected within util.filterImageFromURL

Since I have no time for creating a full PR with a fix, I'm posting my solution here:

export async function filterImageFromURL(inputURL: string) {
  const photo = await Jimp.read(inputURL);
  const outPath = `${__dirname}/tmp/filtered.${Math.floor(
    Math.random() * 2000
  )}.jpg`;
  const processedImage = await photo
    .resize(256, 256) // resize
    .quality(60) // set JPEG quality
    .greyscale() // set greyscale
    .writeAsync(outPath);
  return outPath;

Postman collection is missing to test the REST API.

It is not the collection for the final project, but the Image sharing project.

It will be great if you can add code for exercises from https://github.com/scheeles/cloud-developer/tree/01-start/course-03/

While trying to create the Get function for id i am met with this error

The filterImageFromURL is only working for certain URLs and failing for some valid ones.The server came up with error of could not MIME type for Buffer which originates from Jimp.read
.Please help to resolve this issue

When I'm writing the command 'npm run dev' ,it is showing error and I'm unable to start the server.

Found that jwt library expects the payload to be a plain object. As seen in the course, we send directly the sequelize model instance, which is not a plain object. To solve it, I used the method short() inside the generateJWT method:

function generateJWT(user: User): string {
    return jwt.sign(user.short(), config.jwt.secret);
}

Image URL used: https://timedotcom.files.wordpress.com/2019/03/kitten-report.jpg

Maybe then could use another image to validate the course project?

Hi,

it looks like the S3_CORS.xml file is missing in the basic server folder.

thank you!

I have gotten this in attempting to clone repositories today. I am on the latest version of GitHub Desktop. I have tried launching Desktop from GitHub as well as pasting the URL into Desktop with the same results.

This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version. The most recent version should
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution. Rebooting is also suggested if you
are unable to find another cygwin DLL.

npm run build displays The syntax of the command is incorrect when it gets to the line of code.
"clean": "rimraf www/ || true",
"build": "npm run clean && tsc && cp package.json www/package.json && mkdir www/tmp/ && cd www && zip -r Archive.zip . && cd ..",.

This seems to be the culprit "&& mkdir www/tmp/"
zip -r Archive.zip . throws it's error if you remove the above line

Hey, just like a heads up, when going through the Serverless stuff, forking and attempting to install the node modules for course4 exercises gives you an error.

The reason is because its attempting to snag the AWS, axios, and other packages from the nexus solutions url in the package-lock file., which doesn't work. To fix this on my end, I deleted the package-json and then removed the aws-sdk dependency from the package.json file. Then I just ran 'npm i aws-sdk' which installed the 2.11100 version. Then I ran 'npm i' to install the other packages and their dependencies and to have it auto generate a new package-lock.json file and voila, everything works now.

If you just try to edit the package.json file and add the 2.1110 as the aws-sdk version it will still error out because the other packages in package-lock are pointing to the nexus solutions endpoints rather than npm endpoints.

Hi Gabe, ran "npm install" and received "found 1 high severity vulnerability".

"npm audit" gives link "https://www.npmjs.com/advisories/1146" and recommends package.json updated from "sequelize": "^5.10.0" to "sequelize": "^5.15.1".

Re-running "npm install" resolves issue with "found 0 vulnerabilities".

This causes a hidden Lambda-code exception which I found via testing the CreateImage code from the API Gateway console.

This
const urlExpiration = process.env.SIGNED_URL_EXPIRATION

should be updated to this
const urlExpiration = Number(process.env.SIGNED_URL_EXPIRATION)

There are several issues with the tslint config provided in the projects. Atleast for c2 restapi & frontend.

• The rules directory codelyzer does not exist and fails the build.
• There is a mix of ' and " quotes in the project. " are used in config files, ' mostly in code. The current tslint config treats this as error
• c2 restapi specific
  ** can't run build in lesson 4, part 7, because authentication isn't handled yet and implicit any is used.

I suggest to use a more relaxed tslint config...

Should be "main": "server.js" instead of "main": "src/server.js". Elastic Beanstalk won't put the instance as healthy without this change.

This was required after npm audit fix for the rest backend. I don't know about the original code. Please advise if I can send a PL please, thanks, G.

I had an issue running the udacity-c2-restapi exercise to follow along with the lesson . and I had managed to workaround this and I thought this fix might be helpful for anyone facing the same issue.

Steps :
1- Delete package-lock.json ❌
2. Update all the npm dependencies to their latest version : here's how ✨

Upon running the app you'll face this typescript error. 👇

The easiest way to fix would be by applying this change to FeedItem and User models at:
src\controllers\v0\feed\models\FeedItem.ts
src\controllers\v0\users\models\User.ts

- export class User extends Model<User>
+ export class User extends Model

- export class FeedItem extends Model<FeedItem>
+ export class FeedItem extends Model

Hope this helps 🙂

I have an issue running npm run dev in the udacity-c2-restapi exercise to follow along with the lesson. After filling in my details in the dev object and running npm run dev, the server just runs and closes with no output

• I had cross-checked the secret key and all stuff
• changed version from v4 to v2
• server location is correct.

still in POSTMAN i am getting error, see the image.

utils.filterImageFromURL() is giving below error. How can this be resolved?
