• Why it works on Postman and not on the client code?

The difference is the format of the request. In Postman, you're sending the data as JSON object. While in the client code, you're sending data inside a form-data. They are different. That's why the req.body is empty. Different request formats require the server to parse in different ways.

I see in your code the line //formData.append("thumbnail", newProject.thumbnail); is commented, you prepare to send the project's thumbnail in the request. In this case, you cannot send the request in JSON format. You need to modify the server to make it understand the form data.

For this, I recommend this popular package

Multer is a node.js middleware for handling multipart/form-data, which is primarily used for uploading files.

Did you ensure, back-end side, you were receiving the email and password properly before even trying to match passwords?

I think the problem lies here:

Answering my question here. Based on @Gari Singh's answer above the certificate that you have to use in the "tlsCACerts" parameter in the connection.json file has to be created by combining the intermediate and root CA into a single file. The first block in the file should be the intermediate CA and the second block should be the root CA. This certificate chaining is required because the intermediate CA is signed by the root CA and the client should pass both so that they can be validated properly. Comprehensive explanation can be found here: https://www.thesslstore.com/blog/root-certificates-intermediate/

The final thing that I was missing because of which I was getting the error "Failed to evaluate transaction: Error: Committer must be connectable" was that I was passing 3 orderers in the "channels" section of the config and only passing one of their details in the "orderers" section of the config. Adding the ip and other details for the other 2 orderers took care of that issue.

You can do it by creating a custom _app.jsx file. There you can track the initial visit by adding a useEffect hook with an empty dependency array so that the function will only fire on the initial render:

Well, have you try to load postcss before other linters? (In your config, prettier-loader run before postcss. And you may want to disable those linters (moving to another file as linting is useless in your case, you're trying to lint dependencies)

I use the following for a user / roles association for user management. You can change the model names and properties to suit your needs. For details about model associations, check out this section of the sequelize documentation

Default arguments can be passed to macro, but for blocks it does not seem particularly pretty:

Are you running the migration within the Docker Compose container for your app, or on the Docker host machine?

From the host machine's point of view, there is no such hostname as my-redis (it's only a thing within a Docker overlay network with that container in it).

Since you've exposed the Redis port 6379 to your host (and in fact the whole wide world), you'd use localhost:6379 on the host machine.

There is a bug in ForkTsCheckerWebpackPlugin create-react-app (CRA) uses. Updating it to the latest version (at the time of writing 6.2.10) and using this CRA override solves the issue:
