`go mod download -json` does not product valid json? Is this a known issue or am I missing something?

Do you have an example that shows the invalid json?

I simply run `go mod download -json` and it outputs this (which isn't valid.)

It should be:

[{

 "GoModSum": "h1:Zm6kSWBoL9eyXnKyktHP6abPY2pDugNf5KwzbycvMj4="
},{
...
}]

Notice the array, it's missing in the example above. This means this output can not be parsed.

Hi kalekold,

It looks like it is a stream of JSON objects? 

If so, I suspect this is expected?

See related discussion here (for 'go list -m -u -json' in this case), along with sample code for parsing:

Per the issue you linked, thepudds, absolutely correct.

This comment gives details on how to handle such a stream of JSON objects:
