When creating custom modules, has anyone come across this error before?

**OutputTooBigException: 10005785 byte output rendered, over limit of 10000000 bytes**

I had no idea there was a file size limit to custom modules!

I’m creating a new custom module that references a big HubDB table (over 580 rows and growing) and because of the size, I have embedded various conditions / lightboxes / filters etc!  
This error is stopping me adding the final conditions to the page or finishing the styling.  
Any help would be appreciated.

Hi @ben-duchy ,

I also didn’t know there was a size limit! But if I’m reading it right, that size limit is **10 MB**. That seems like a lot!

I’d check you don’t have any bugs in any loops in your code that are re-rendering things many times more than they should.

Otherwise… maybe you could break up the module into smaller sub-modules?

If you can share more of the code here, maybe someone can advise in more detail - otherwise I’d raise a ticket with support and let someone take a more in-depth look.

Cheers,

Mike

Hi @mike-ward,

You’re absolutely right, just this minute I found a couple of bugs in the code that was trying to loop everything x5 so it was struggling and maxing out.
