portable plugin create command error: fail to install plugin: missing mirror

[yoiberdev]

Can you help me implement a go plugin on ekuiper 1.14.7-dev or any other version?
I always get this error every time I try to register a plugin or a portable even with a zip that I download from the ekuiper documentation itself as mirror.zip from "sdk/go/example/mirror"

yoiber@yoiber:~/Downloads/mirror-portable$ docker cp mirror.zip edgex-kuiper:/kuiper/plugins/portable/
Successfully copied 16.4kB to edgex-kuiper:/kuiper/plugins/portable/
yoiber@yoiber:~/Downloads/mirror-portable$ curl -X POST http://localhost:59720/plugins/portables -H "Content-Type: application/json" -d '{
"name": "sumFunction",
"file": "file:///kuiper/plugins/portable/mirror.zip"
}'
{"error":1000,"message":"portable plugin create command error: fail to install plugin: missing or invalid json file sumFunction.json, found 17 files in total"}
yoiber@yoiber:~/Downloads/mirror-portable$

Does it have to do with the fact that I use edgex-foundry as the main container?
I would appreciate it if you could send me a zip to register as a plugin to use as an example

@yoiberdev The plugin json file must in the root of the zip file. It is likely that you only have a directory in the root. There should be no directory, only files in the root.
