500: Request header too large

[sawant-ankeeta]

Hi Team,

We have encountered an error in Presto Gateway and need assistance with modifying a property in the gateway configuration to increase the header size. Can you provide help on which property to modify for this purpose?

+1. I also see this issue. Do we have some place to set it?
