Random error: "mev-share service error"

Hey, I started using flashbots recently and from time to time I’m getting the following error from the RPC when trying to submit the bundle. I specified all builders from this list. It’s worth noting that this error appears randomly. The tx I’m submitting into the bundle simulates fine (not running bundle simulation though). If I try to send a simple transfer transaction as a bundle (for testing purposes), it will occasionally throw the error I mentioned.

The error mentioned appears to be defined in the mev-share-node code. However, my bundle is submitted using eth_sendBundle method not sure why it would even do anything MEV share related.
