@tuxcanfly, JFYI, it's a gateway issue, not rpc

[Wondertan]

However, this does not seem to be an actual problem on celestia-node side:

• I double-checked the code, and we don't set any restrictions on the size
• The linked failed test is in go-cnc, not the node.

Considering these two facts, I am closing the issue.

I think the celestia-node RPC* is broken b/c celestiaorg/docs#781 (comment) so will wait until that is resolved.

Also related #2300 and #2301

@rootulp, Josh meant RPC is broken, not the gateway

Fixed comment above.
