OAI 500 Error

[Joyner Library]

Dear DSpace Community,

We got a report that someone was trying to access oai records at

https://thescholarship.ecu.edu/server/oai/request?verb=ListRecords&metadataPrefix=oai_dc&set=com_10342_122

but received a 500 error. Please help me troubleshoot this error.

I noticed an error in the tomcat logs but don't know what file or record to edit.

  SXXP0003: Error reported by XML parser: Invalid byte 1 of 1-byte UTF-8 sequence.
Error on line 7 column 158
  SXXP0003: Error reported by XML parser: Invalid byte 1 of 1-byte UTF-8 sequence.
Error on line 1 column 2084 

I have attached the dspace log because it has a more detailed version of the error.

Thank you,

Nick

Hello Nick,

OAI configuration is located under dspace/config/crosswalks/oai

All of these files are XML (or XML-based XSL Transformations), so the
error message implies that some the these XML files is invalid.
Candidates include

- xoai.xml or description.xml that include general configuration e.g.
regarding metadata formats, or
- metadataFormats/oai_dc.xsl that provides the logic for oai_dc format.

Please check these with XML validator/parser and correct if needed - or
compare with default ones such as
https://github.com/DSpace/DSpace/blob/dspace-7_x/dspace/config/crosswalks/oai/metadataFormats/oai_dc.xsl

Best regards,

I'd also check that your XML files are encoded correctly using UTF-8.
