I noticed that some barcode types gracefully handle invalid data with a message: > Invalid barcode value for qrcode format Some types completely lock up the designer/browser tab. I'm not sure if I could do some of my own error handling to make this fail more gracefully but I suspect the component should be updated. This is a simple view that will let you click through the [types](https://docs.inductiveautomation.com/docs/8.1/appendix/components/perspective-components/perspective-display-palette/perspective-barcode#barcode-specification-options). The first one to lock up for me is "codablockf": [perspectiveBarcodeErrorHandling.zip](https://forum.inductiveautomation.com/uploads/short-url/luahgxJyduocanJlPr0IwIZsxEg.zip) (45.5 KB) ---

We have an internal ticket to update the library in use for the Barcode Component. There is no ETA at this time.
