I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.
Expected Behavior
I am using Open-WebUI along with CapacitorJS to load the HTML pages statically and change the backend API. With this approach I am able to fetch chats, model, do authentication etc.,
Now, when I send a message I should get a streamed response
Actual Behavior
I am not getting the streamed response. Instead I get the following error
SyntaxError: The string did not match the expected pattern
// Only redirect API calls
const originalFetch = window.fetch;
window.fetch = function(url, options = {}) {
if (typeof url === 'string' && url.startsWith('/')) {
url = BACKEND_URL + url;
}
// Force credentials to 'omit' to work with wildcard CORS
options = options || {};
options.credentials = 'omit';
return originalFetch(url, options);
};
// Fix WebSocket connections
const OriginalWebSocket = window.WebSocket;
window.WebSocket = function(url, protocols) {
// Replace capacitor WebSocket URLs with backend URL
if (typeof url === 'string') {
if (url.includes('ws://capacitor') || url.includes('wss://capacitor')) {
url = url.replace(/wss?:\/\/capacitor/, WS_URL);
} else if (url.startsWith('/')) {
url = WS_URL + url;
}
}
console.log('WebSocket connecting to:', url);
return new OriginalWebSocket(url, protocols);
};
// Preserve WebSocket static properties
Object.setPrototypeOf(window.WebSocket, OriginalWebSocket);
window.WebSocket.prototype = OriginalWebSocket.prototype;
window.WebSocket.CONNECTING = 0;
window.WebSocket.OPEN = 1;
window.WebSocket.CLOSING = 2;
window.WebSocket.CLOSED = 3;
})();`
