Error Spot_market_id 2048 since 1.0.2 that create order in the Perps Market

Spot order error creating order in the Perps

Spot order doesn't work and do Perp order

Description

Since the update of the lighter_sdk in Python, I get a weird error when creating an order in the Spot market_id ETH/USDC 2048.

That always creates the order and positions on Perps, even with this market_id of the Spot ETH.
Anyone getting the same? It was working well in version 1.0.0 of the Python SDK.

My script is working well in 1.0.0.

This broke in the 1.0.2 version and always sends the order to the Perps ETH market_id.

@MSghais Update to the latest SDK and try to run the examples, may be you are using older version of python SDK.

Where can we get the latest compatible version—PyPI tag, GitHub release/tag, or a specific commit/PR to checkout?

Release 1.0.2

Release 1.0.2

We’re already on the latest lighter-python main / tag v1.0.2 (same as you suggested). Using a real mainnet account we can read positions fine, but all tx operations (create order / reduce-only close / cancel) are rejected by /api/v1/sendTx with 21136 invalid PublicKey (sometimes 21120 invalid signature).
We verified /api/v1/apikeys?account_index=... returns api_key_index=1 and the returned public_key matches our local key, so it doesn’t look like wrong credentials. Also reproduced via different network routes (direct + proxy).
Could you point to a newer signer binary / commit / release compatible with current mainnet, or clarify the exact tx_info PublicKey field format/name the backend expects?
