v8.1.11

I keep getting this error when I try to decode a JSON object from a response body:

```auto
Traceback (most recent call last):
  File "<input>", line 14, in <module>
ValueError: Unable to parse response body as JSON: com.inductiveautomation.ignition.common.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 2 column 2 path $

```

Here is my script:

```python
client = system.net.httpClient()
url = "https://api.dailymotion.com/file/upload"
headers = {
	"Accept": "application/json",
	"Accept-Encoding": "gzip, deflate, br",
	"Authorization": "Bearer <TOKEN>"
}
res = client.get(url, headers=headers)
print res.good # returns True

```

Is there any way I can fix this?

Is it actually malformed? Do you have an example of it?

Not in Postman. Here is the response:

```json
{
    "upload_url": "<url>",
    "progress_url": "<url>"
}

```

Can you post your whole script? The error references line 14 but there’s not 14 lines in the script you posted.

It was this line (I cleaned it up when I added to post above):

```python
print res.getJson() # res.json returns the same thing

```

Here is what else I tried (based on SO answers):

```python
from com.inductiveautomation.ignition.common.gson import GsonBuilder
client = system.net.httpClient()
altGson = GsonBuilder().setLenient().create()
client.setGson(altGson)
...

```

Same thing happens.

Hmm, I was going to suggest basically that:

```auto
new_gson = client.getGson().newBuilder().setLenient().create()
client.setGson(new_gson)

```

Try printing `str(res.getBody())` or something instead.

</div>

`getBody()` returns data, as far as I can tell. I added the code you included above but still get the same error when I try to `getJson()`.

Also, this is happening in the script console, if that matters. It wasn’t working on a button event, so I’m now investigating.

Does the above print out the JSON you’re getting or just a string rep of the bytes?

Might need something like this instead:

```auto
from java.lang import String

print String(res.getBody())

```

Trying to see the contents of the body without parsing it.

A bunch of gibberish (even though response says it is UTF-8 encoded).

Huh. Not sure what else to try. You probably _are_ getting a body that isn’t JSON, but I don’t know why.

A little facepalm for future readers: there is a `getText()` method on the response object.

Okay, one last suggestion: remove your gzip/deflate/br headers.
