How can I resolve a 'Request Header or Cookie Too Large' error?

Last Updated:   |  Applicable Viz Versions: All


This error typically occurs when a user opens over 20 tabs causing the cookie header to be too large. This error may cause any unsaved changes to be lost. 

As a best practice, we recommend not opening more than 20 tabs in a window and opening additional Viz tabs in an incognito window.
