GP builder: some pdb files result in 400 error.

Try 8QQJ. You get to the options page, but when you pick a glycan to add and click submit you immediately get:
400 Error Occurred. Bad request, please try again.

I suspected file size, but I can add a glycan to 6HOF (12mb) and it works.

In 8QQJ, removing the HETATM doesn't help, but additionally removing the first J chain fixes the issue and I get a downloadable glycoprotein. However, having just the J and A chain works ok too so it's not the J chain itself.

@Lachele do you have any insight or see what might be triggering the 400?
