AA50 postOp reverted

The paymaster contract's postOp function reverted.

Possible Solutions

  1. If you are using a paymaster service, contract them.
  2. If you are running your own paymaster, check that you have correctly implemented the postOp function. If you do not plan to use the postOp function, check that you have not set the context parameter in the validatePaymasterUserOp function.
