Urgent help is needed with uploading the game to the host — more work afterwards.

Budget: 85 EUR Deadline: 2 days

Hello!
My name is Alexandra, I am engaged in game development and optimization, deployment on Vercel, testing, and bug finding on different devices. I am ready to promptly help with your problem.

What I will do:

I will upload the game to Vercel correctly, with the proper configuration.

I will find the cause of the error "json parse error: unexpected identifier 'undefined'" — it is usually related to:
• incorrect import paths
• JSON parsing errors
• global variables
• browser or device incompatibility

I will test the game on several devices (phone, tablet, PC) to reproduce the problem.

I will fix the error and provide recommendations on how to avoid it in future builds.

If necessary, I will optimize the build and project structure.

I work quickly — I can start right now, usually such errors are resolved within a few hours. Expand

Good morning,

I am interested in your need for large format stickers. After receiving the measurements and photos, I can prepare a print-ready design in professional quality, taking into account all technical details.

I offer a **quote of 1200 PLN net** for a complete set of stickers with a completion time of **5 working days**.

I work based on proven methods for preparing graphics for large format printing, ensuring optimal color quality and fitting to dimensions.

I have experience in executing similar projects for various industries, which allows me to quickly and efficiently prepare final materials ready for production.

I would be happy to schedule a short online meeting to discuss the details and advise on the best solutions for your stickers. Expand

Hi, I'm a Vercel + JS dev. Fixed JSON parse errors like "undefined" in live games. Issue often from async data or device-specific caching. I'll deploy your game to Vercel, test on iOS/Android, fix the bug in

Good day

I understand the task, I need to help correctly upload the game to Vercel, reproduce and fix the error "JSON Parse error: Unexpected identifier 'undefined'", which appears only on some devices, and ensure that the game runs stably afterwards.

How I see the work
1. Setting up the project and deployment on Vercel
1.1 I will check the project structure, build scripts, environment
1.2 I will set up deployment on Vercel, check routing, paths to assets, environment variables

2. Finding the cause of the JSON error
2.1 I will pinpoint the location where JSON.parse is called and add temporary logging to see what exactly is coming as undefined
2.2 I will check the differences across devices and browsers, mobile Safari, Chrome, desktop, to reproduce the bug
2.3 I will check data sources, localStorage, fetch to the backend, static files, to rule out different response formats

3. Fixing
3.1 I will add safe parsing, checks for undefined and incorrect data
3.2 If necessary, I will adjust the data format from the server or the logic of saving in localStorage, so that valid JSON is received on all devices
3.3 I will remove temporary logs and tidy up the code

4. Testing
4.1 I will run the main game scenario on several devices and browsers until the error appears
4.2 After the fix, I will check that there are no pop-up errors, the game does not crash, and data is read correctly
4.3 I will prepare a short report on what exactly was the cause and what changes were made

Deadline and cost:
1. The assessment and fix of the specific error along with the deployment setup on Vercel usually takes 4-8 working hours
2. The budget is around $80-150, if it turns out that the problem is deeper (for example, if a significant rewrite of the data storage logic is needed), we will agree on a new ceiling before starting the revisions

To estimate more accurately and start right away:
1. What stack is the game made on, pure JS, React, Phaser, or something else?
2. Is there a repository on GitHub or GitLab, or do we need to work from a project archive?
3. Does the error appear immediately upon entering the game or after a specific action, bet, resource loading?
4. Is a separate test project on Vercel needed, or will we fix the currently functioning one?

I am ready to get involved, analyze the project, set up deployment on Vercel, and bring the game to a stable launch without errors. Expand
