> I'm trying to create Airflow variables using a json file. I am trying to import airflow variables using UI(webserver) when I upload the json file I get this error "Missing file or syntax error" and when I try to upload using airflow cli not all the variables gets uploaded properly. The catch is that I have a list of dictionary in my json file, say
>  ex:
>  {
>  "demo_archivedir": "/home/ubuntu/folders/archive",
>  "demo_filepattern": [
> { "id": "reference", "pattern": "Sample Data.xlsx" }
> ,
> { "id": "sale", "pattern": "Sales.xlsx" }
> ],
>  "demo_sourcepath": "/home/ubuntu/folders/input",
>  "demo_workdir": "/home/ubuntu/folders/working"
>  }
> I've attached two images
> img1. Using airflow variables cli command I was able to create partial variables from my json file(airflow_cli.png)img2. After inserting logs in the "airflow/bin/cli.py" file, I got this error. (airflow_cli2_crop.png)
> The thing is I gave this value through the Admin UI one by one and it worked. Then I exported those same variable using "airflow variables" cli command and tried importing them, still it failed and the above mentioned error still occurs.
> Note:
>    I am using Python 3.5 with Airflow version 1.8
