easyeda2kicad - unsupported format with project.json Kicad v7.0

Hi,
I get the following error message after loading the 'project.json' file from the project backup zip.

Q: is this the correct json file to use with this? 

**WOKWI error msg:**
```
Running easyeda2kicad v1.9.5:
Reading file project.json...
Parsing content...
Error: unsupported file format
