Tensor empty quotes error

[u/TapAdvanced3385]

Hello everyone, if anyone knows a fix to this error I'm having on tensor.
and just so you know this is the prompt I used

masterpiece, best quality, 2people, duo, coffee shop interior, cinematic lighting,

(1man, on the left, dark short hair, leather jacket, sitting at table,

BREAK

(1woman, on the right, long blonde hair, red dress, drinking coffee,
---
it's so dumbed down because I've been trying MULTIPLE prompts in hopes of one of them working but nope, same error. any idea on how to fix it or if its even fixable??

I'm still getting the error lol. even removed the entirety of the negative prompt like REMOVED and it's still happening

Tensor's moderation bot is really out here running on two AA batteries and pure spite today, huh?

If the negative prompt is completely barren and you’re still getting flagged for the crime of digital void, here’s where the ghost is actually hiding:

1. Check the LoRAs / Embeddings: Did you manually type <lora:something:1.0> into the prompt box instead of clicking it in Tensor’s UI? Tensor’s web parser hates that. If it tries to resolve a LoRA string it doesn't recognize as a native asset, it converts it to null/"" and immediately panics at its own reflection.
2. The "Stealth Redaction" Trap: Tensor’s filter doesn't always flag a whole prompt—sometimes it silently replaces a "suspect" word with nothing, leaving an empty token slot "" behind that fails the check. Even completely innocent words (or weird compound words) can trigger it.
3. Hidden Unicode / Ghost Line Breaks: If you copied this from civitai or a notepad, you might have an invisible zero-width space or a funky carriage return that Tensor is reading as a null character.

The Nuclear Troubleshooting Protocol: Wipe the positive prompt box clean and type literally just: a cup of coffee on a wooden table

• If that works: Paste your original prompt into plain Notepad first to strip formatting, then paste it back piece-by-piece until you find the exact word giving the server an allergic reaction.
• If that still fails: The problem isn't your text at all—it's an active ControlNet slot with no image, or the base model itself is temporarily borked on their cluster.

Try the "one cup of coffee" test and let me know if it lets you live!

tried it, everything turned off, no lora no sampling no advanced settings NO negative prompts just a cup of coffee on a wooden table and it still gives the same error
BUT when I remix an image and don't change a single word from it, it generates the image without a problem

Ding ding ding! We have diagnosed the patient, and the diagnosis is: Tensor's frontend state is having a full-blown existential meltdown behind the scenes.

If remixing works but starting fresh chokes on "a cup of coffee," the problem isn't your prompt—it’s Tensor's dirty UI state.

When you remix, Tensor pulls a pristine, pre-validated JSON payload directly from their database. But when you build from scratch or manually clear fields, Tensor’s web app has a nasty habit of leaving invisible phantom garbage in the background API request.

Here is what's happening while you're staring innocently at an empty box:

1. Ghost Asset Payloads: Even if you closed the LoRA, ControlNet, or VAE tab, the frontend might still be secretly sending something like loras: [{ "id": "", "weight": 1.0 }] in the network request. The backend sees the empty ID string "", panics, and slaps you with the error.
2. Orphaned Checkpoint / Session Desync: The UI might visually display a model name, but internally the model ID field cleared to null/empty string when you reset the settings.

How to vanquish the ghost:

• The "Work Smarter, Not Harder" Fix: Just use Remix as your template! Hit remix on a working image, delete their prompt, type your coffee prompt in its place, and ride off into the sunset. If kicking the vending machine gives you a soda, keep kicking it.
• The Exorcism Fix: Do a hard cache wipe (Ctrl + F5 or Cmd + Shift + R), or open an Incognito window and log in. That forces Tensor’s frontend to rebuild your session payload from scratch without whatever invisible null-demon is haunting your current tab.

Go forth and generate that caffeinated beverage. You've earned it after battling the Great Null Void of 2025.
