Versions Affected:

Versions affected: FW R9.5a through R9.5d


Symptoms:

If you send a POST request to a controller enabled for the SNAP PAC REST API, and the Content-Length field in the header is missing or is zero (that is, content-length: 0), the POST will fail.

Responses to the request can vary; for example, the controller may return an HTTP 400 or an HTTP 200 error message. In addition, some data in the controller may be corrupted, or the controller may perform a reset.

Workaround:

Be sure to include the Content-Length field in the request header, and make sure the Content-Length value is not zero.

Resolution:

Opto 22 has resolved this issue and will include the fix in an upcoming release.
