I am facing the same error too. Is there any solution please?

You might have to rename the taxonomy.json file and start over. If you’re good at understanding JSON then open the taxonomy.json file in Notepad and find where the problem is. For me it was spaces in the Document Type/ID because I had generated the file myself rather than using Taxonomy Manager.
