Error during upgrade: No AST nodes of type ContractDefinition with id 419 found

Support SDK
#1

I am trying to upgrade a contract instance on kovan. I added a single function and then used the cli tool to upgrade the contracts. This is the steps that I took

oz compile
*selected kovan network
*selected contract instance
*picked the instance to upgrade

Then I get this error message:

No AST nodes of type ContractDefinition with id 419 found.

:computer: Environment

running on mac, these are my deps from package.json:
“@openzeppelin/contracts-ethereum-package”: “2.5.0”,
“@openzeppelin/upgrades”: “^2.6.0”,
“@openzeppelin/cli”: “2.8.2”,
“openzeppelin-solidity”: “^3.0.1”,

Compiling gives me some warnings but it shows a checkmark and says contracts have been compiled successfully.

Any help would be appreciated!

I have tried deleting both the build and the artifacts folder and that didn’t help.

Hi @elliot,

Welcome to the community forum :wave:
Thanks for posting here.

Are you able to share your contract (or a cut down version) so that I can reproduce?

Hi @elliot,

Thanks for letting me know that you can’t share your contract.

I am not sure what is causing the error.

You have “@openzeppelin/contracts-ethereum-package”: “2.5.0” which is the upgradeable version of OpenZeppelin Contracts using Solidity 0.5
You also have “openzeppelin-solidity”: “^3.0.1” which is OpenZeppelin Contracts using Solidity 0.6.

I assume that you are using Solidity 0.5, so you don’t need to have openzeppelin-solidity (the old name for @openzeppelin/contracts) as a dependency.

You may want to try going through the simple example in the Learn guides to rule out anything in your config: https://docs.openzeppelin.com/learn/upgrading-smart-contracts#upgrading-a-contract-via-cli

Are you able to share the imports of your contract so that I can try to reproduce? If not, I suggest creating a new project with a simple contract with your imports to see if that is causing the issue.

I removed “openzeppelin-solidity”: “^3.0.1” and now none of the dependency solidity files are being properly imported. I deleted package-lock.json, removed build folder, removed node_modules, did a fresh npm install and it is saying other openzeppelin dependencies (ownable) cannot be found.

These are all of my dependencies in package.json:

I figured out the issue. I had two versions of a contract in my build folder which was causing deployments to fail.

Hi @elliot,

I’m glad you were able to track it down.

This error should only happen on partial compilations.
Deleting build/contracts directory and recompiling should resolve the issue.
