Problem is fixed in version: PAC firmware R9.5d

Symptoms:

If you try to post a JSON string that includes whitespace (other than the normal ASCII space character), the SNAP PAC REST API may not be able to post the string. When this happens, the API returns a -8 error code.

Examples of whitespace that can cause this issue include the ASCII characters CR (carriage return) and LF (line feed).

For example, this JSON string won't cause an error:
{"value": "hello"}

...but this JSON string will cause a -8 error to be returned:
{ "value": "hello" }
