Unexpected Server Error with JavaScript

[tempcoderr]

What version of Remix are you using?

1.7.4

Steps to Reproduce

I created a Remix app using the npx create-remix@latest command and then choosing Just the basics and then Remix App Server and then JavaScript, But when I then run the server it gives me the following error:

Unexpected Server Error

TypeError: isbot is not a function

If instead of Javascript I choose Typescript, the app works fine.

Expected Behavior

The app should load and run.

Actual Behavior

Gives an Unexpected Server Error error.

Hi @tempcoderr, I could not reproduce the issue, see complete installation log below.
isbot is used in app/entry.server.jsx and is listed as a dependency in package.json

Did you run npm install ?

🍺  ~ $ npx create-remix@latest

I created a new Remix app and the issue still persists. Here is the process which I followed:

Could you check if you have isbot in your node_modules? What version got installed? What does console.log(isbot) right after its import in server entry yields?

[tempcoderr]

There is an isbot folder in the node_modules folder, and its version is 3.6.2. When I write the following statement,

const isbot = require("isbot").default;
console.log("isbot", isbot);

It returns isbot undefined.

[machour]

And what about:

const isbot = require("isbot");
console.log("isbot", isbot)

Also, what node version are you running? 🙏

[tempcoderr]

@machour Thanks for the reply. After changing const isbot = require("isbot").default; to const isbot = require("isbot");, the app has started and is working fine, and the value of isbot becomes isbot [Function: isbot].

[machour]

Thank you for the feedback 🙌🏼

@MichaelDeBoey do you know what might be going wrong with the TS => JS conversion here?

[aayushbisen]

I also face this issue today.

Remix Version: 1.7.5
Node Version: v18.12.0

Changing const isbot = require("isbot").default to const isbot = require("isbot") fixed the issue.

[PhilipHassialis]

I also face this issue today.

Remix Version: 1.7.5 Node Version: v18.12.0

Changing const isbot = require("isbot").default to const isbot = require("isbot") fixed the issue.

Can confirm similar behaviour.

Remix v. 1.7.5

Node version 16.13.1

Selected "Just the basics", "Remix Server", "Javascript". As soon as I changed the isbot require, the server automatically re-rendered index.jsx and it was displayed properly in the browser.

[cbenjamin2009]

I can confirm the same behavior is happening when choosing "Just the Basics" with "Remix Server" and "JavaScript". Remove the '.default;' from 'entry.server.jsx' on the 'const isbot = require("isbot")' line solves the problem.

[machour]

@sannamalai176 this seems like another problem. Can you open a new discussion (Q&A category) please? 🙏🏼

[machour]

@moutafatin1 Your error message have nothing to do with this issue. Please open a new question in the Discussions tab.

[alexnguyennz]

I can confirm the same behavior is happening when choosing "Just the Basics" with "Remix Server" and "JavaScript". Remove the '.default;' from 'entry.server.jsx' on the 'const isbot = require("isbot")' line solves the problem.

+1 this is still happening with these exact options.

We were able to narrow down this issue to be related to some weirdness with jscodeshift in certain environments in this thread: https://discord.com/channels/770287896669978684/1046094365426208818

[pcattori]

jscodeshift was removed as a dependency a couple version ago and this is no longer reproducible on recent versions (e.g. 1.19.2).
