Unable to open the TTL file created on WebVowl #192

Hi team, I had created an Ontology last week and saved it in Turtle format. Now when I am trying to open the same TTL file by uploading it in WebVowl, I am getting the below error.

Retrieving ontology from file: NewOntology (3).ttl Parsing ontology with OWL API ... failed

Loading process failed: Problem parsing inputstream:ontology23953225855189922 Could not parse ontology. Either a suitable parser could not be found, or parsing failed.

Failed to load ontology Failed to convert the file. Server answer: { "timestamp": 1661227200610, "status": 500, "error": "Internal Server Error", "exception": "java.lang.IllegalStateException", "message": "java.lang.NullPointerException", "path": "/webvowl/convert" NewOntology (3).zip

}

Same issue I'm facing again, making use of the online service https://service.tib.eu/webvowl/
