Faulty/corrupted objects are found, these cannot be opened or deleted in AWI.
At the open attempt the following message appears:
"Object view could not be loaded"
Upon deletion, when selecting the context menu - nothing happens and the following error is logged in the AWI log:
2025-11-19 11:45:56,884 pool-2-thread-116 [ERROR] <SYSTEM>:<CLIEBT>/<USER>/<DEPARTMENT 1A7042BBD2598BC1E0B6B93A936862E6-0 0000000001028030 [com.uc4.ecc.framework.core.pool.ContextAwareExecutorService] - Unhandled Exception in Async Call:
com.uc4.api.InvalidUC4NameException: Invalid Object/Alias name: '1001007k\<FOLDER>'. Allowed characters are: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.$_@#/-'. Maximal allowed length is: 200.
Strangely the mentioned folder object ('1001007k\<FOLDER>') is found in another client and should not interfere with the objects in question.
This issue could appear after a client was created with Client Copy.
When AWI opens an object, it looks up in the database which user created or last modified the object.
In the rare cases, where (i) such user doesn't exist anymore and (ii) the OH_idnr is re-used by a folder (with database structure <parent_OH_Idnr>\<folder>), an error occurs because no backslash is expected.
