# AUR0207 ## Error Message `AUR0207: Trying to enter an active connectable` ## Description This error occurs when the connectable switcher attempts to enter a connectable that is already active. This usually indicates mismatched enter/exit calls (for example, entering twice without exiting). ## Troubleshooting * Check custom observation code for balanced enter/exit calls. * If this occurs without custom integrations, please report it with a reproduction. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
