Let’s move from theory to practice. Follow these diagnostic steps in order.
At its core, OpenBullet is a tool that uses Configs (.loli or .opk files) to define a testing workflow. Each config expects a specific type of input data.
OpenBullet supports three primary data types for each line in your combolist (the list of credentials or data you are testing):
The error occurs when the data format in your combolist does not match what the config is programmed to parse. For example, you feed a config expecting User:Pass a combolist formatted as Email:Pass, or you feed it an Auto config a standard User:Pass file.
Many advanced configs use the "Auto" data type. These configs expect a very specific number of columns. For example, a config for a gift card checker might require CardNumber|ExpiryMonth|ExpiryYear|CVV. If you provide a simple CardNumber:CVV pair, the config will throw this error because it cannot find the 3rd or 4th variable.
If you have spent any time using OpenBullet (or its more modern forks like OpenBullet 2 or SilverBullet) for web testing, automation, or security auditing, you have likely encountered the dreaded red error message in the logs: "This config does not support the provided input" (sometimes variably phrased as "Openbullet this config does not support the provided").
For new users, this error is a dead end. For experienced pentesters, it is a frustrating mismatch between your data and the configuration file’s logic. This article will dissect exactly what this error means, why it happens across different OpenBullet versions, and how to fix it step-by-step.
Bad wordlist:
user1@example.com
user2@example.com
Fix: Convert your emails to combos using a text editor or OpenBullet's built-in wordlist tools. Add a dummy or placeholder password. For example, use "Find & Replace" to replace newline (\n) with :dummy\n. Result:
user1@example.com:dummy
user2@example.com:dummy
Note: This only allows you to run the config; the actual login will likely fail unless the site ignores the password field.

If you spend time working with OpenBullet (OB) or OpenBullet 2, you know the feeling: you’ve found a promising config, loaded your wordlist, set your proxies, and hit "Start." But instead of the satisfying "HIT" notifications, you are immediately greeted by a wall of red text in the logger:
"This config does not support the provided input format."
It is one of the most common errors for beginners and intermediate users alike. It usually stops your run dead in the tracks before it even begins.
In this post, we are going to break down exactly what this error means, why it happens, and how to fix it so you can get your checks running smoothly.
Before fixing the error, you must understand it. OpenBullet works on a simple principle: A Config defines how to process data, and a Wordlist provides what data to process.
The error "This config does not support the provided..." is OpenBullet’s way of saying: "The data format in your input file does not match the data format the config was designed to eat." Openbullet This Config Does Not Support The Provided
In simpler terms, imagine a vending machine (the config) designed to accept only quarters (data type). If you insert a dime, a nickel, or a dollar bill, the machine rejects it. OpenBullet is rejecting your input because the config's "data type" requirement does not match the "data type" of the lines in your wordlist.
The full error message usually specifies what is missing or mismatched. Common completions of the sentence include:
