hey! Any idea on why I get this error : `HttpError: Bad Gateway ` from `node_modules/starknet/dist/provider/default.js:217`? I may be rate limited because I am using it inside checkpoint indexer but I doubt because I dont even spam it.

Also got this : `Error: Could not POST from endpoint https://alpha4.starknet.io/feeder_gateway/call_contract?blockNumber=pending: request to https://alpha4.starknet.io/feeder_gateway/call_contract?blockNumber=pending failed, reason: socket hang up`

does cross-chain bridge produce its own block? or it only verify the blocks from A/B chain?

Hey guys,

I am having issue with generating _abi.json file when I use namespace,
Please see example below.

Does someone know solution of how to generate _abi.json file when namespace is used? I really need help 🙏 

This code generates starknet_abi.json

%lang starknet
from starkware.cairo.common.cairo_builtins import HashBuiltin
from starkware.starknet.common.syscalls import get_caller_address

@External
   func store_name{syscall_ptr: felt, pedersen_ptr: HashBuiltin, range_check_ptr}(_count: felt) -> (even : felt) {
      alloc_locals;
      local even;

      let (caller) = get_caller_address();
      if (_count == 2) {
         even = 1;
      }
      return (even=even);
   }
=============================================================
This code does not generates starknet_abi.json (please see use of  namespace)

%lang starknet
from starkware.cairo.common.cairo_builtins import HashBuiltin
from starkware.starknet.common.syscalls import get_caller_address

namespace ToMoon {
@External
   func store_name{syscall_ptr: felt, pedersen_ptr: HashBuiltin, range_check_ptr}(_count: felt) -> (even : felt) {
      alloc_locals;
      local even;

      let (caller) = get_caller_address();
      if (_count == 2) {
         even = 1;
      }
      return (even=even);
   }
}

Is there a plan to get better visibility when a transaction got received but not placed into a block?
For the moment we only know that it is RECEIVED but have no clue if it’s been discarded because of missing constructor params or if it’s just late:

```python
{
	transaction_hash: '0x3d26af3d7a8f17ea28c2a71a250fd8c5dcd162b779051fd36a3bfcd9f130fab',
	actual_fee: undefined,
	status: 'RECEIVED',
	status_data: undefined,
	messages_sent: [],
	events: [],
	l1_origin_message: undefined
}
```

upd: I noticed we are notified when we make an error, but:

1. we don’t know what’s happening between `RECEIVED` and `REJECTED | ACCEPTED_ON_L2`, it’d be nice to be able to monitor a bit more preceisely where’s the transaction in the pipeline

2. the error message is often cryptic and not human readable, ex:

```python
Error: REJECTED: TRANSACTION_FAILED
Error at pc=0:1073:
An ASSERT_EQ instruction failed: 9:6 != 9:5.
```

Is there a way / tool to be able to debug this kind of failed transactions?
