Embedded variable VS general attribute

Hello,

I have a weird situation where I am passing a variable into a module that is not getting interpreted correctly.  When the variable is passed into the module, I receive an error.  When the variable is embedded into the module, works as expected.

Orchestrator 7.0.1.17606 build 3571217

Code:

//var re = /(([^\-]*)\-(\d{2})(\d{2})(\d{2})(.)\-(GE|SR))/;
var re = datastoreFilterRegEx;
System.debug("DEBUG_LOG_Module=FindDatastore: var re= " + re);
var m;
var targetDatastore = [];
var len = datastores.length;
for (i = 0; i < len; i++) {    var str = datastores[i].name;    //Debug        if (debugOutput == true) {            System.debug("DEBUG_LOG_Module=FindDatastore: var str = " + str);        }    if ((m = re.exec(str)) !== null) {            //Debug                if (debugOutput == true) {                    System.debug("DEBUG_LOG_Module=FindDatastore: var m = " + m);                }        var volumeName = m[0];        var sanName = m[2];        var arrayType = m[3];        var diskType = m[4];        var diskRaid = m[5];        var volumeUse = m[6];        var volumeAccess = m[7];            //Debug                if (debugOutput == true) {                    System.debug("DEBUG_LOG_Module=FindDatastore: volumeName: " + volumeName);                    System.debug("DEBUG_LOG_Module=FindDatastore: sanName: " + sanName);                    System.debug("DEBUG_LOG_Module=FindDatastore: arrayType: " + arrayType);                    System.debug("DEBUG_LOG_Module=FindDatastore: diskType: " + diskType);                    System.debug("DEBUG_LOG_Module=FindDatastore: diskRaid: " + diskRaid);                    System.debug("DEBUG_LOG_Module=FindDatastore: volumeUse: " + volumeUse);                    System.debug("DEBUG_LOG_Module=FindDatastore: volumeAccess: " + volumeAccess);                }        if (volumeAccess === "SR") {            //Debug                if (debugOutput == true) {                    System.debug("DEBUG_LOG_Module=FindDatastore: Datastore is not suitable: " + datastores[i].name);                }            re.lastIndex++;        }        if (volumeAccess === "GE") {            System.log("This datastore is a possibility: " + datastores[i].name);            targetDatastore.push(datastores[i]);        }    }
}

Log output:

Problem:

• Line 01 has the variable as if it was embedded.  If I uncomment that line and comment out line 02, the module completes fine.
• The log shows the variable as the same (text wise) as the embedded variable but it does not like it.
  • It is being interpreted as a function but cannot figure out why

Thanks
