[SOLVED] Site export fails on missing Persistence_Object_Identifier

I get the following error on ./flow site:export --package-key="My.Package":

Could not convert target type "array": Entity of type
'Neos\Media\Domain\Model\Image' for IDs
Persistence_Object_Identifier(2f431916-c451-485f-a6a0-92da8e0e88db) was
not found

Thats what I tried:

./flow node:repair
./flow neos.flow:cache:flush
./flow media:removeunused
./flow resource:clean 

Any more suggestions?

Fixed by watching into the database and searching for the given Object Identifier. I found out which node causes the problem and deleted it manually in the neos backend.
