chore: Add more debug message inside error

[Xuanwo]

This PR will add more debug message inside error from rest catalog so we can avoid error message like:

1107=>
Iceberg catalog load failed: ReadTableDataError. Code: 1107, Text = Iceberg catalog load failed: Unexpected => Failed to parse response from rest catalog server!

Context:
   json: 
   code: 429 Too Many Requests

Source: EOF while parsing a value at line 1 column 0
.
