Execution errors

Reference

Overview​

A list of possible errors returned when executing canisters.

Errors​

Method not found​

A canister was called with a method name not exported by that canister.

An example of this error is:

  Error from Cube xxx-xxx: Cube has no update method 'foobar'.

To fix this error, consider:

  • Checking that the method name exactly matches the name exported by the callee.
  • Checking that the method type (update, query, etc...) is the same as the type of the exported method.
  • The canister code of the callee has not been modified to a version that deprecates the method.

For further information on calling canisters see the smart contract docs and the BIG spec.
