Unexpected Data Type change between Thing and Stream Service

I have some strange behavior that I can't tell what I may be doing wrong.

I have a Stream with a service that deletes stream entries that match a field query for the same value.

this service takes an input string var named SR_Num.

CODE:

STREAM: DELETE ENTRY CODE

var srTable = me.FindSr();

var IDs = []

if (srTable.length > 0){

    for(var i=0; i< srTable.length;i++){

        var thisID = srTable.getRow(i).id;

        IDs.push(thisID);

        me.DeleteStreamEntry({streamEntryId:thisID});

    }

}

result = "Deleted " + srTable.length + " entries. " + IDs.join(", ");

From My Thing I have a timer subscription that updates the stream from an info table but first calls this Delete Service

CODE:

THING: UPDATE STREAM CODE

...

for(var i=0;i<SRTable.length;i++){

        var row = SRTable.getRow(i);

        logger.warn("SR Number: " + row.SR);

        //Delete Existing SRStream entries for SR

        Things["SRStream"].DeleteSrFromStream({SR_Num:

row.SR

});

...

The Issue:

When I send a STRING "63918566" (Verified with a logger.warn call ) to the service DeleteSRFromStream.

DeleteSRFromStream gets the STRING "6.3921924E7" appears that the string is converted to a number for some reason.

work around:

I found a workaround by adding a char at the start of the string to prevent the conversion to a number that appears to be happening.

Example: Send "_63918566" Get "_63918566"

Is there something I'm doing wrong or is there a bug some place?

Re: Unexpected Data Type change between Thing and Stream Service

The JavaScript tried to convert string to number. Can you log logger.warn(typeof row.SR) too ?

You would need to reconvert to string with .toString()
