Rest 500 because of "java.io.EOFException: No content to map to Object due to end of input"

Artur I'm New Here Dec 03, 2020

Hello dear community,
I am loosing some hair over this:

I have so far written several Rest Put requests in Katalon Studio for updating certain report pages in Confluence.

3/4 cases work - the one which includes writting Issues / Exceptions et cetera fails.
I noticed it may be because of "{" and "}" resulting in makros.
Because of several reasons, I wanted to fix this by using a makro, the hope being that it would result in no errors, no matter what passes through.


The current Json string is valid via e.g. https://jsonformatter.curiousconcept.com/#

In the Rest body value field I am writing markups / tables via HTML. In one of the table fields I am using a noformat markup (though I already tested multiple markups with no success).
Now I can paste the HTML part (by hand) into the HTML Editor of a confluence page(<>)  and it will work like a charm.

I have tried several methods to reduce issues:
- replaceAll( problematicCharacters.. ) or 
- cap the String of each field to 100 chars
- etc.

Though it all seems fine, I still keep getting REST 500  / "java.io.EOFException: No content to map to Object due to end of input"

It is surely no general server error since I can send different request resulting in 200.

My Rest String right before passing it to HttpConnection is:

{ "version": { "number": "169"}, "title":"_NOT_OK_", "type": "page", "body": {"storage":{"value": "<p>TEST RESULTS Mobile 'NOT OK' from DATE</p><table><colgroup><col /><col /><col /><col /><col /><col /></colgroup><tbody><tr><th><p>OS</p></th><th><p>Stage</p></th><th><p>Testsuite</p></th><th><p>Testcase</p></th><th><p>Testresult</p></th><th><p>Date</p></th><th><p>Details</p></th></tr><tr><td><p>ANDROID</p></td><td><p>PRE</p></td><td><p>XYApp</p></td><td><p>XY</p></td><td><p>FAIL</p></td><td><p>2020-12-03 10:05:18</p></td><td><div class='content-wrapper'> <p class='auto-cursor-target'><br/></p><ac:structured-macro ac:macro-id='33d138b1-6273-4af9-937f-e9fa3c9b91ad' ac:name='noformat' ac:schema-version='1'><ac:parameter ac:name='nopanel'>true</ac:parameter><ac:plain-text-body><![CDATA[ org.openqa.selenium.WebDriverException: [ERROR MESSAGE] Returned value cannot be converted to WebEle ]]></ac:plain-text-body></ac:structured-macro><p class='auto-cursor-target'></p></div></td></tr><tr><td><p>ANDROID</p></td><td><p>PRE</p></td><td><p>XY App</p></td><td><p>TC_XY</p></td><td><p>FAIL</p></td><td><p>2020-12-03 09:55:04</p></td><td><div class='content-wrapper'> <p class='auto-cursor-target'><br/></p><ac:structured-macro ac:macro-id='33d138b1-6273-4af9-937f-e9fa3c9b91ad' ac:name='noformat' ac:schema-version='1'><ac:parameter ac:name='nopanel'>true</ac:parameter><ac:plain-text-body><![CDATA[ org.openqa.selenium.WebDriverException: [ERROR MESSAGE] Returned value cannot be converted to WebEle ]]></ac:plain-text-body></ac:structured-macro><p class='auto-cursor-target'></p></div></td></tr><tr><td><p>ANDROID</p></td><td><p>PRE</p></td><td><p>XY  App</p></td><td><p>XY TESTCASE</p></td><td><p>FAIL</p></td><td><p>2020-12-03 09:53:00</p></td><td><div class='content-wrapper'> <p class='auto-cursor-target'><br/></p><ac:structured-macro ac:macro-id='33d138b1-6273-4af9-937f-e9fa3c9b91ad' ac:name='noformat' ac:schema-version='1'><ac:parameter ac:name='nopanel'>true</ac:parameter><ac:plain-text-body><![CDATA[ org.openqa.selenium.WebDriverException: [ERROR MESSAGE] Returned value cannot be converted to WebEle ]]></ac:plain-text-body></ac:structured-macro><p class='auto-cursor-target'></p></div></td></tr></tbody></table>", "representation": "storage" }}}

Thanks in advance.

I guess I am a step further since my colleague successfully tested my REST String with a chrome REST expansion.

In his opinion, it's the Java class HttpURLConnection, that seems to produce issues - even though I could send similar, but more simple PUT requests.

He recommends using http://javadox.com/org.codehaus.groovy.modules.http-builder/http-builder/0.6/groovyx/net/http/RESTClient.html
