Error saying " Cross-Process JS call failed...

Post by curlytop010100 » Fri Oct 28, 2016 10:44 am


My Imacros is acting very strangley I never encountered this problem in Imacros since using it for 4 years. An error always says "Error: cross-process JS call failed...(Error code:-1001) when clicking a particular link like:

TAG POS=1 TYPE=A ATTR=ID:mainForm:tab_custodianAccounts:0:link_custodianAccountId

or clicking similar to a next button in a website, example:

TAG POS=1 TYPE=IMG ATTR=SRC: ... rd-new.png

This hasn't happened before . Really appreciate any help.

Same error here :(
W7x64, iMacros for FF 8.9.7, FFv47.0.2 (i know my browser is a couple versions old but I'm afraid to update it..could this be the issue?)

All I'm doing is extracting a table as html, spliting it up and doing a for loop.
Oddly enough, iMacros does it's job good, the rest of the code seems to be broken.
So I have a for loop going through each <tr> from a table and trying to output the value with an alert.
I'm also using regex to remove all tags.

My error is Error: cross-process JS call failed, line -380 (Error code: -991)

-991 = Javascript parsing/evaluation error (i guess i need to triple check my js
-1001 = Unknown error (this is for curlytop010100)

var goToWebsite_macro = "CODE: URL GOTO=" + "\n";

var tbl_xpath = "//div[@id='content']/table[1]/tbody";
var extract_tbl_macro = "CODE: TAG XPATH=" + '"' + tbl_xpath + '"' + " EXTRACT=HTM" + "\n";

alert(iimGetLastExtract()); //this works fine

var arrTableRows = iimGetLastExtract().split('<tr');
for(let i=2; i<5; i++)
alert(arrTableRows);//getting the error here I guess
