If you link a issue collector in Jira and you copy the code:

var urlCollector2 = "https://xxxxxxxl.atlassian.net/s/7b778cfebf13decc5456f71fc9929dc0-T/es_ESyzq2go/6327/12/1.4.11/_/download/batch/com.atlassian.jira.collector.plugin.jira-issue-collector-plugin:issuecollector/com.atlassian.jira.collector.plugin.jira-issue-collector-plugin:issuecollector.js?locale=es-ES?collectorId=54be172c";

You have to remove "?locale=es-ES" if you want than issue collector work.
