dogma returns error invalid json when called dogma cat --jsonpath

[wingyplus]

These steps below I copied from tutorial.

Reproduce steps:

start centraldogma with docker command:

$ docker run -p 36462:36462 --name dogma --rm line/centraldogma

Then running with following steps:

$ cat test.sh
#!/bin/sh

conn='http://localhost:36462'

./dogma -c $conn new projFoo
./dogma -c $conn new projFoo/repoA
echo '{"a":"b"}' > a.json
./dogma -c $conn put projFoo/repoA/samples/a.json a.json -m 'Add a.json'
./dogma -c $conn ls
./dogma -c $conn cat projFoo/repoA/samples/a.json
./dogma -c $conn cat --jsonpath '$.a' projFoo/repoA/samples/a.json

Expected result:

The ./dogma -c http://localhost:36462 cat --jsonpath '$.a' in the last step should returns "b" as mentioned in tutorial website.

Actual Result

invalid character 'b' looking for beginning of value

Dogma version:

$ ./dogma
Central Dogma version 0.41.1 (241c5a8)

And found it in current master branch.

Thanks for the report. Let me take a look it soon.

I capturing response body that come from centraldogma service (run via docker):

{"revision":2,"path":"/samples/a.json","type":"JSON","content":"b","url":"/api/v1/projects/projFoo/repos/repoA/contents/samples/a.json"}

The content return "b". If we want to return "b" as tutorial mentioned, content must be "\"b\"".

Is it bug on centraldogma service?

I read test code from https://github.com/line/centraldogma/blob/master/server/src/test/java/com/linecorp/centraldogma/server/internal/api/ContentServiceV1Test.java#L276. Looks like it's intention.

@minwoox Is it possible that UnmarshalJSON strip " out of content by using json.Unmarshal?

@wingyplus Sorry about the late response. Was on a business trip and couldn't take care of this issue.
Let me just reproduce it. Thanks!
BTW, are you using Central Dogma?

[wingyplus]

@minwoox Sorry for disturbing you. I see it using inside LINE Man Team (but another team not my team). And I interesting to use it in my personal project. :)

@wingyplus Ah that's cool! If you want to talk directly, you can use the company slack #help_centraldogma. :-)
