KeyError brain in getObject Plone 6

I received this error because of some issues with portal catalog. A folder containing images was deleted but the catalog was not updated correctly. my-obj-path was just one of the 899 images.

I created in Management Interface a python script to find all broken brains:

catalog = context.portal_catalog
brains = catalog('my-obj-path')
broken = []

for brain in brains:
    try:
        obj = brain.getObject()
    except Exception:
        broken.append(brain.getPath())

print(broken)
print("Count: ")
print(len(broken))
return printed

Then, the solution was to go to Catalog and press Update catalog. After 2 minutes, the problem was solved.
