I think you want to store <code>[ : "opted_in" ]</code> into a string variable so use this: 

<blockquote>
 String optionValue= vars.get("Optinurl");
</blockquote>

into your beanshell assertion
and if you want only <code>opted_in</code> to store in to a variable then use 

<blockquote>
 String optionValue= vars.get("Optinurl_1");
</blockquote>

<li>The error you're getting is not connected with your <code>Optinurl</code> variable initialization. Looking into

It appears you have some syntax error in the very first script line. So the options are:

<ul>
<li>Double check your code, make sure that parentheses, quotation marks, etc. are matching, statements are ending with semicolon, quotation marks in strings are escaped, etc. </li>
<li>Adding <code>debug();</code> line as the first line of your script produces comprehensive debug output to STDOUT</li>
<li>Surrounding your code into <a href="https://docs.oracle.com/javase/tutorial/essential/exceptions/catch.html" rel="nofollow">try/catch block</a> allows to having more informative error stracktraces</li>
</ul></li>

Thanks Dmitri, Kaushlendra for replying. 

I updated my script as below and it is working fine in GUI/command line. Since vars.get("Optinurl") returns ["opted_in"], so had to remove quotes and square brackets before comparing Strings. 

<pre><code>String optinValue = vars.get("Optinurl"). replace("[","").replace("]","").replace("\"","");
String expectedState = "${EXPECTED_STATE}";

log.info(optinValue);
log.info(expectedState);

if(!optinValue.equals(expectedState)){
 Failure = true;
 FailureMessage = "Values of state field for Campaign id " + "${CAMPAIGN_ID}" + " dont match "; 
</code></pre>

} 

I could not use String optinValue = vars.get("Optinurl_1") because it fails when i run tests from command line (works fine in GUI mode though)

I have to assert JSON response of an API. 
So extracted value of a field (state) using JSON path extractor and save it in variable (Optinurl) 

"state":"opted_in"

In the Debug Sampler, i see the value of Optinurl as

Optinurl=
[
: "opted_in"
]

Optinurl_1=opted_in

Optinurl_matchNr=1

When i try to retrieve value of variable Optinurl in Beanshell assertion as below, 

String optinValue = ${Optinurl}

i get 

ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: <code>String optinValue = '["opted_in"]';'' Token Parsing Error: Lexical error at line 1, column 23. Encountered: "\"" (34), after : "\'["

Thanks for your help in advance !
