Vue warn Unhandled error during execution of onShow at Devicelist__pageId=4__pagePath=pageshomeapplydevicelist__pageQuery=clientId046C59C60FF2 191559959 TypeError Cannot read property open of undefine

This warning message is indicating that there is an error occurring during the execution of the onShow event in a Vue component. The error is specifically related to trying to access the open property of an undefined object.

To fix this issue, you need to investigate the code in the onShow event and determine why the object that is being accessed is undefined. It is possible that the object is not properly initialized or assigned a value before the onShow event is triggered.

Once you identify the cause of the issue, you can update your code to ensure that the object is properly defined and has the open property before attempting to access it.
