I tried this with chrome:

{code:javascript}
 | Uncaught exception: Uncaught TypeError: Cannot read property 'createElement' of undefined (http://localhost:8080/business-central/verifier/dtableVerifier/DDFC3D4453CB85BB71197C4DE2FF626C.cache.js:2609:75)
{code}

and firefox

{code:javascript}
 | Uncaught exception: TypeError: b is undefined (http://localhost:8080/business-central/verifier/dtableVerifier/DDFC3D4453CB85BB71197C4DE2FF626C.cache.js:2609) | Uncaught exception: TypeError: b is undefined (http://localhost:8080/business-central/verifier/dtableVerifier/DDFC3D4453CB85BB71197C4DE2FF626C.cache.js:2609)
{code}

So seems not related with chrome.

Seing the stack trace from chrome:

formatted code is:

{code:javascript}
function Qb(a) {
    var b, c, d;
    d = !a.c ? (Ob(),
    window) : a.c;
    b = (Ob(),
    d.document);
    c = b.createElement('script');
    Pb(c, a.b);
    (b.head || b.getElementsByTagName('head')[0]).appendChild(c);
    a.a && (c.parentNode.removeChild(c),
    undefined);
    return c
}
{code}

this is generated code by gwt http://www.gwtproject.org/overview.html so the real code is under.

drools-wb-services/drools-wb-verifier/drools-wb-verifier-webworker/src/main/java/org/drools/workbench/services/verifier/plugin/backend/DecisionTableVerifierWebWorkerProvider.java

Not sure if in code itself or in gwt translation

Any idea on what to check, debug or test to fix this?
