AP sync AC version upgrade fail

After upgrading the AC version to WX3800X-CMW910-R1411P01 at a certain site, it was necessary to restart the AP to synchronize the AC version to WA6500A-CMW710-R2595P30. However, the upgrade failed, and the version remained the old one.

Configuration check revealed that AC has firmware version verification enabled (firmware-upgrade enable), and no wlan apdb configuration was found. Logs indicate errors:
Failed to open the image file.Reason:wa6500a.ipe is not exist.
Checking the apimge directory under flash revealed files for wa6500a:

However, another version of wa6500a was also found in the root directory during inspection:
 42 -rw-    53877760 May 26 2023 17:54:12   wa6500a.ipe

Further verification confirmed that the site is configured to retrieve ipe files for specific APs from the AC root directory:
wlan image-load filepath local 

Delete the error wa6500a.ipe in the root directory and resolve after removing the wlan image-load filepath local configuration
