On my side, I built a simple reproducer which seems to work as expected. Below is some additional information which lists the stored types associated with the types whose dictionaries were not found: Instead it might be the type of a data member, base class, wrapped type, or other object needed by a stored type. Also include the class header in classes.h A type listed above might or might not be the same as a type stored in the Event (or Lumi or Run). For example, if this class has any transient members, you need to specify them in classes_def.xml. Please add (or move) the specification ‘’ to the appropriate classes_def.xml file along with any other information needed there. Begin Fatal Exception 1 08:14:48 CEST- An exception of category ‘DictionaryNotFound’ occurred while Constructing the EventProcessor Calling ProductRegistry::initializeLookupTables Exception Message: No data dictionary found for the following classes: _uniq_ptr_impl > default_delete tuple > unique_ptr > Most likely each dictionary was never generated, but it may be that it was generated in the wrong package. Removing std::unique_ptr from classes_def.xml results in error when reading back root file which makes use of dictionary generated without std::unique_ptr:
