[Fixed] 🚨 Bug: Cannot Create or Edit Projects – Always “Internal Server Error” (Owner/Admin, ChatGPT Teams, Chrome/Windows)

[martin.fuerholz]

Summary:

As the Organization Owner and Admin of a ChatGPT Teams account, I am currently unable to create new projects or edit existing ones. All attempts to create or modify a project (name, instructions, etc.) immediately result in an Internal Server Error (HTTP 500). This issue persists across browsers, sessions, and systems.

This report includes full reproduction steps, timestamp, environment details, and a screenshot showing the exact error in both UI and browser console.

Environment Details:

Item	Value
Platform	ChatGPT Web App (https://chatgpt.com)
Plan	ChatGPT Teams
Browser	Google Chrome 135 (64-bit)
OS	Windows 10 Pro
Location	Germany
User Role	Organization Owner & Admin
3rd Party Cookies	Enabled
Browser Extensions / VPN	None (disabled)
Alternative Browsers Tried	Yes (same result)
Private Mode Tested	Yes (same result)
Re-login Performed	Yes

Steps to Reproduce:

1. Open ChatGPT Web App
2. Go to Projects
3. Click the + (“New project”) button
4. Enter a project name
5. Click Create project

→ Immediately results in:

“Internal Server Error” (displayed in UI)
HTTP 500 in browser console

Same issue occurs when attempting to:

• Edit an existing project’s name
• Add or edit project instructions

Error Timestamp:

22 April 2025, 20:30 CEST (UTC+2)

Request URL:

https://chatgpt.com/backend-api/gizmos/snorlax/upsert

---

Screenshot:

A screenshot showing both the UI error and the network console error (500) has been attached.

---

Why this should be escalated:

• The error occurs consistently and reproducibly
• All standard troubleshooting steps have been exhausted
• User is the Org Owner with full permissions
• No browser / network / extension interference present
• The endpoint gizmos/snorlax/upsert returns 500 without client-side fault

---

Please escalate this issue to the relevant engineering team. I’m happy to provide further debug info if needed (e.g. request/response headers or trace ID).

Thank you!

Facing the same issue, I am a Plus user, I only have two existing projects but I am unable to create a new project.

[cmac77]

Same problem for me except I am on Windows 11 and using the Pro plan.

[Mr_Grumpy]

Same with the addition of also not being able to add new or delete current project files.

[Alessandroooo]

Same here, I thought it was because I reached the limit of projects, but even after deleting 2 of them (and refreshing the page multiple times) it still says “Internal Server Error”.

Someone found a solution yet?

[Argos57]

The very Same for me.
Tried to logo out/log back in.
Chrome and firefox, same “internal server error”

[ztunes]

Same issue for me, “Internal Server Error”

I am a Pro user and experiencing the same thing. Can’t create any new GPTs or edit existing ones without receiving the “Internal Service Error” notification and then all my work is deleted.

I have the same issue. I can’t create a new project. I can delete projects but not save a new one.

Probably it is related to:

Errors with saving Custom GPTs - OpenAI Status

[martin.fuerholz]

Update: The “Edit Projects” part is fixed now. Haven’t tested the other issues.
Especially the other comments about similar issues when editing custom GPTs.
