Error: Fetcher: Unsupported dialect of XML: not RDF or XHTML namespace, etc. <?xml version="1.0" encoding="utf-8" ?> <feed xmlns="http://www.w3.org/2005/A 

at Fetcher.failFetch 

 at XMLHandler.parse (https://timbl.com/timbl/Automation/Library/Mashup/mashlib.js:9994:22) at https://timbl.com/timbl/Automation/Library/Mashup/mashlib.js:11543:24 at async Promise.all (index 8)
store = context.session.store

The XML resource starts:

<?xml version="1.0" encoding="utf-8" ?>
