Not sure if the issue is due to missing the id field in the jsonrpc call,

If I try locally
curl -s https://api.developer.coinbase.com/rpc/v1/base-sepolia/
-H "Content-Type: application/json"
-d '{"method":"eth_call","params":[{"data":"0x250b1b4100000000000000000000000000000000000000000000000000000000000000400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000100000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000020000000000000000000000000AB5ACC57FB1B38D74A5EcB6a33da8CFDc2ce207d","to":"0x0ba5ed0c6aa8c49038f819e587e2633c4a9f428a"},"latest"]}'

I get this response, with id as null which is probably why parsing is failing
{"id":null,"jsonrpc":"2.0","result":"0x0000000000000000000000008ebfb11cbc1c0e3a14b998698ffef075732923c0"}%

but if I include the jsonrps version and id then I get the following response

curl -s https://api.developer.coinbase.com/rpc/v1/base-sepolia/
-H "Content-Type: application/json"
-d '{"jsonrpc": "2.0", "id": 1, "method":"eth_call","params":[{"data":"0x250b1b4100000000000000000000000000000000000000000000000000000000000000400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000100000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000020000000000000000000000000754e49da4978bd9FF2e9Bfddd9399898FbB3dEc3","to":"0x0ba5ed0c6aa8c49038f819e587e2633c4a9f428a"},"latest"]}

{"id":1,"jsonrpc":"2.0","result":"0x0000000000000000000000001fcef92e1fe743d6e99cb38d757482d74ccb196d"}
