rpc http_request getblock err

I'm testing the Bitcoin network locally using Test4.
When I use http_request post the getblock method, an error occurs.
For ease of testing, I added a quick get_block validation call to main and tried multiple times.
The max_response_bytes limit is clearly set in the code.
I tested rpc other methods behaved normally, such as get_block_hash

• Error Output
  rpc error: SysFatal => Http body exceeds size limit of 1999999 bytes.; will retry with an extra 25231479988 cycles.

• Request hash
  0000000000000000fe191c2bd95b92591fb55e282a91e2605ea0d2bf64495ec0
