Assert: *** Failed to process file json data, error: invalid character '}' looking for beginning of object key string

[Soenhay]

I just downloaded the program and created a basic config file. I also installed Graphviz. Following are the details:

Command: protodot.exe -src protoFileName.proto

config.json:

{
    "locations": {
        "graphviz": "C:\\Program Files\\Graphviz 2.44.1\\bin"
    },
    "options": {
        "generate .png file": true,
        "generate .svg file": false,
    }
}

Error message:

Assert: *** Failed to process file json data, error: invalid character '}' looking for beginning of object key string
Error: failed to load config file

The graphviz option needs the full path to the dot.exe.

I changed the config file to be a copy of the one in the repo except for my paths and now I get this error:

I tried running dot manually like this and got another error:

>"C:\\Program Files\\Graphviz\\bin\\dot.exe" -v
dot - graphviz version 2.44.1 (20200629.0846)
There is no layout engine support for "dot"
Perhaps "dot -c" needs to be run (with installer's privileges) to register the plugins?

Then ran it again with admin privilege's and it it worked.

After doing that, the first command in this post works and the images are generated at ${HOME}/protodot/generate.

Pretty cool!
