I’m having trouble with the bundling feature in MVC4 for my JavaScript files. When I run the app, I get this error:
Uncaught SyntaxError: Unexpected token <
It’s weird because everything works fine when I set debug="true". I’m not sure what’s causing this.
Does anyone know how to fix this error? Or is there a way to turn off bundling just for scripts?
Update: I figured it out! The problem was that my bundle name was the same as a directory name. I changed the bundle name and now it’s working. Just wanted to share in case anyone else runs into this issue.
Wow, that’s a tricky one you stumbled upon! I’m super curious about how you narrowed it down to the naming conflict. Did you have any particular debugging steps that led you to that realization?
I’ve run into bundling issues before, but never quite like that. It’s pretty sneaky how it only shows up in production mode, right? Makes me wonder what other gotchas might be lurking out there in the MVC bundling world.
Have you encountered any other weird bundling quirks since then? I feel like there’s always something new to learn with these build processes.
Thanks for sharing your solution! It’s always awesome when folks come back to update their posts. You never know when it might save someone else hours of head-scratching.
I encountered a similar bundling issue in a previous project and discovered that naming conflicts are a common cause. When the bundle name matches an existing directory or file name, the system can become confused which leads to unexpected errors in production. I eventually resolved it by renaming the bundle and confirming that all paths in the BundleConfig.cs file were accurate. It also helped to clear the browser cache and use the BundleTable.EnableOptimizations property during troubleshooting. Thought these insights might be useful if you ever face a similar problem.
glad u figured it out! i had a similar issue once. its tricky cuz it works in debug mode but not in production. good catch on the naming conflict - thats a sneaky one. thanks for sharing the solution, might save someone else a headache down the road!
