Kadene transfer-create call fails

Question

I'm trying to call transfer 10 K tokens to account k:81df193e0d913bc87e127150efdaaee39584abbd2d0223ed8c9afb0b31cf9db2, with transfer-create function. However it fails and the error message is here =>

Javascript function call

transfer-create implementation in the pact contract is

  ;; ; --------------------------------------------------------------------------
  ;; ; Fungible-v2 Implementation

  (defun transfer-create:string
    ( sender:string
      receiver:string
      receiver-guard:guard
      amount:decimal )

    @doc " Transfer to an account, creating it if it does not exist. "

    @model [ (property (conserves-mass amount))
             (property (> amount 0.0))
             (property (valid-account-id sender))
             (property (valid-account-id receiver))
             (property (!= sender receiver)) ]

    (with-capability (TRANSFER sender receiver amount)
      (debit sender amount)
      (credit receiver receiver-guard amount)
    )
  )

This happens because a recent change in the node software. For stability the logs are no longer written on the blockchain. To obtain an error message for your transaction you should first run it using the /local preview endpoint.

See also release notes for the node software: https://github.com/kadena-io/chainweb-node/releases/tag/2.17
