Exporting in list view by applying filter [which creates tiny url] is stuck on "Please confirm, loading"Issue Export Stuck on "Please Confirm, Loading" Page When attempting to export records from the list view by applying a filter (e.g., "serialnumber is one of") and querying thousands of records, the process gets stuck on the "Please confirm, loading" page. Upon reviewing the logs, the following error is observed: 2023-12-21 19:08:05 (555) Default-thread-1 SEVERE *** ERROR *** ClassUtil - class not found: null 2023-12-21 19:08:05 (556) Default-thread-1 SEVERE *** ERROR *** java.lang.NullPointerException java.lang.NullPointerException at com.glide.processors.xmlhttp.RenderInfo.init(RenderInfo.java:65) at com.glide.processors.XMLHttpProcessor.processJavaAJAX(XMLHttpProcessor.java:155) at com.glide.processors.XMLHttpProcessor.process(XMLHttpProcessor.java:121) at com.glide.processors.AProcessor.runProcessor(AProcessor.java:668) at com.glide.processors.AProcessor.processTransaction(AProcessor.java:287) at com.glide.processors.ProcessorRegistry.process0(ProcessorRegistry.java:184) at com.glide.processors.ProcessorRegistry.process(ProcessorRegistry.java:172) at com.glide.ui.GlideServletTransaction.process(GlideServletTransaction.java:51) SymptomsFilter Distortion When Export Fails When attempting to export data with a non-functional filter, clicking the funnel icon results in the filter being distorted, prompting you to reapply the filter. However, for a functional filter, clicking the funnel icon retains the filter conditions as expected. ReleaseNACauseThis could be due to one of the records having an invalid reference.Same error can be observed in a different scenario:https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0783412Recommendations:Determine differences between records in working compared to non-working lists and review references in those which are not included in the working list. Illegal characters like %01 (Hex 0x01, ASCII SOH) in the long URL [tiny url] cause the export process to fail. Cleaning the filter by removing problematic serial numbers should resolves the issue.ResolutionIdentify the full filter in the URL: Locate the full URL in the sys_tiny_url table using the sysparm_tiny value.Search for illegal characters in the full URL string, particularly after specific serial numbers. For example, %2C(comma) may be followed by %01 (ASCII control character, "Start of Header"), which is invalid. Example of a problematic full URL string:...59D1282NLK%2C%015VD1206RSQ%2C...Identify the serial number causing the issue. In the example above, the serial number starting with SVD12 contained an illegal character that appended %01 to the URL.Remove the specific serial number(s) containing illegal or special characters from the filter of thousands of serial numbers.Retry the export after removing problematic entries.
