WS.sendRequest ConnectionClosedException when handling gzip encoded rest response

[kazurayam]

See the following post:

Katalon repsonse size smaller than Postman response size?

I just guess, Postman and Katalon Studio behaves differently when the response has a header: Content-Encoding: gzip The size of raw gzipped response will be far smaller (624 bytes) than the original text message (4KB). KS might be showing the size of raw bytes. Postman might be showing the unzipped text size. I just guess.

I think that Katalon Studio does not work with WS respose with a header Content-Type: gzip.

You have options:

1. Change your Web Service so that it stops using Content-Type: gzip and test it with KS.
2. Keeep the Web Service as is, test it using other tools that support Content-Type: gzip appropriately.
