What causes "response.message ? t(response.message) : 'Error uploading file'" in RocketChat/Rocket.Chat?

Re-authorize the WebDAV account under Account settings so fresh credentials are stored (the most common fix)

response.message ? t(response.message) : 'Error uploading fi

Error message

response.message ? t(response.message) : 'Error uploading file'

What it means

Thrown when uploadFileToWebdav returns success:false — the WebDAV server rejected the PUT request (auth failure, wrong path, 4xx/5xx). The thrown message is response.message passed through t() if it matches a translation key, otherwise the literal 'Error uploading file'; the catch turns it into an error toast.

Solutions

Re-authorize the WebDAV account under Account settings so fresh credentials are stored (the most common fix)
Verify the WebDAV server URL is reachable from the Rocket.Chat server and the target folder is writable (test with an external WebDAV client)
Inspect response.message — the WebDAV server's status text — to identify the exact HTTP failure

Defensive patterns

Strategy: try-catch

Validate before calling

const probe = await uploadFileToWebdav(accountId, new ArrayBuffer(0), '.probe');
if (!probe.success) {
	/* surface credential/path problem before the real upload */
}

Try / catch

try {
	const response = await uploadFileToWebdav(accountId, arrayBuffer, title);
	if (!response.success) {
		// inspect response.message for the WebDAV status text before deciding
		dispatchToastMessage({ type: 'error', message: response.message || 'Error uploading file' });
	}
} catch (error) {
	dispatchToastMessage({ type: 'error', message: error });
}

Prevention

Re-authorize the WebDAV account after any password change
Verify the WebDAV URL and folder permissions with an independent client before integrating
Treat success:false as a WebDAV-side failure: log response.message to identify the HTTP status

When it happens

Trigger: Stored WebDAV account credentials are wrong or the password was rotated since authorization; the WebDAV server URL or folder path is incorrect; the server returns 401/403/404/409/507; network/proxy failure between Rocket.Chat and the WebDAV host.

Common situations: Password changed after the account was linked, WebDAV endpoint moved behind a VPN/proxy, target folder permissions revoked, server disk full, self-signed certificate rejected.
