### Description of Issue
TypeError in /lib/renderer/renderer.js. I am working on ExpressJS, using VueJS. If I am in a page of my site (it happens in all of them), if I refresh the page once, everything works. If I refresh it again, then I got a TypeError in renderer.js.
### Stack Trace / Console Log

### Additional Comments
I am sorry for not being really explicit explaining my error, but I am not really sure why it is happening. But if you need any extra info, let me know and I will post it.
Also, meanwhile I fixed it replacing line 415 in the renderer.js file with these lines:
`let cachedBundleError = false;`
`try{`
`let tmp = cachedBundle.data();`
` }catch(e){`
`console.warn("There was a cachedBundle.data() error...");`
`cachedBundle = true;`
`}`
`if (cachedBundle===false && cachedBundle) {`
But obviously it is just a workaround meanwhile a fix is found.
Thanks in advance!
