PUT Body empty when sending lots of data in the Body

[Robert Nelson]

We use Guzzle quite successfully, but we came across an issue when using PUT.

I have PUT request which sends the body successfully to a REST service (PHP based). 

However, when the BODY of the PUT request is a certain size or greater, the BODY on at the REST service appears empty.

I have verified that the body stays intact until the moment of transfer.

Is this an issue with Guzzle or maybe a php config issue?

Upon further inspection, ti looks like the receiving service is dropping the body at a certain size threshold. Ignore this question.

Upon further FURTHER inspection. The request coming from guzzle seems to be removing the body and marking the CONTENT_TYPE as null.

I'm digging into it further. I have since changed this particular call to POST instead of PUT, and still no change.

Turns out we are using an older version of GuzzleHttp. There is a size limit when it turns the body from a string to a stream:

if (($size !== null && $size < 32768)

There was not great way to override this, so we just changed it to what the latest version of GuzzleHttp has.
