[dspace-tech] Error 500 on submission

[Michael Plate]

Hi,

we are facing a serious error on submitting a workspace item
First: the item gets into the system via SAF and is added like this



Metadata contains a title and some text from OCR an 3 PDF files.



The interface is set to German lang.





In the browser console is a 500 internal error and the log says







Anyone else ?

Michael

~/bin/dspace import --add --eperson=XXXXX --collection=123456789/22 --source=. --mapfile=map -w -n -p Then the metadata is edited through the workflow and extended by author, date of submission, language and so on. There is always a yellow circle atop right in the step with an exclamation mark, but this only says "warnings" - nothing more or less. Very often, bu not always, the Item cannot be saved for the next step with an error like "could not be submitted, try later". 2023-05-04 18:02:25,920 INFO 43d49670-c5d7-454f-a2df-068371ebcf88 881b078e-6bd7-4658-91ba-c619dfaed9fe org.dspace.content.MetadataValueServiceImpl @ xxxxxxxxxx::add_metadatavalue:metadata_value_id=3172 2023-05-04 18:02:25,921 ERROR 43d49670-c5d7-454f-a2df-068371ebcf88 881b078e-6bd7-4658-91ba-c619dfaed9fe org.dspace.app.rest.submit.SubmissionService @ [Assertion failed] - this collection must not be empty: it must contain at least 1 element java.lang.IllegalArgumentException: [Assertion failed] - this collection must not be empty: it must contain at least 1 element at org.springframework.util.Assert.notEmpty(Assert.java:470) ~[spring-core-5.3.20.jar:5.3.20] Sometimes one can try later (means: edit it again), some times it works ootb .
