Etherscan request times out when requesting constructor args

[BruceChar]

I followed the instructions but failed.

Running truffle-plugin-verify v0.4.0
Verifying Token
Reading artifact file at E:\MyProject\BlockChain\truffle-contracts\abis/Token.json
Retrieving constructor parameters from https://api-ropsten.etherscan.io/api?apiKey=my_api_key&module=account&action=txlist&address=0x4C9D6ed005bfB301726cA23adE690890B853fB60&page=1&sort=asc&offset=1
Failed to connect to Etherscan API at url https://api-ropsten.etherscan.io/api
Failed to verify 1 contract(s): Token

It seems the network problem. But It migrated successfully. when I try to connect to the verify url, it returns right:

PS E:\MyProject\BlockChain\truffle-contracts> curl https://api-ropsten.etherscan.io/api

Thanks!

Hmm that is interesting. When I copy the link in your debug logs (https://api-ropsten.etherscan.io/api?apiKey=my_api_key&module=account&action=txlist&address=0x4C9D6ed005bfB301726cA23adE690890B853fB60&page=1&sort=asc&offset=1) and replace "my_api_key" with my own API key, the request works.

Are you sure you set up your Etherscan API key in your truffle-config.js correctly?

module.exports = {
  /* ... rest of truffle-config */

  api_keys: {
    etherscan: 'MY_API_KEY'
  }
}

I should probably update the plugin to display the Etherscan response message to the debug logs so that it shows why the request failed 😅

[BruceChar]

@rkalis Yes！I have set up my Etherscan API key in truffle-config.js.

  plugins: [
    'truffle-plugin-verify'
  ],

  api_keys: {
    etherscan: process.env.ETHSCAN_API_KEY
  }

and in file .env

ETHSCAN_API_KEY="MY_API_KEY"

[rkalis]

Can you try going to this link (https://api-ropsten.etherscan.io/api?apiKey=my_api_key&module=account&action=txlist&address=0x4C9D6ed005bfB301726cA23adE690890B853fB60&page=1&sort=asc&offset=1), with your api key filled in?

Browser or curl should work.

Alternatively, do you have a repository that I can look at to reproduce this issue?

yes!

Please provide some more information. Do you have a repository that can reproduce this issue? Can you run the verify command using the --debug flag and paste output?

Could you tell me what happens if you enter the link above (api-rinkeby.etherscan.io/api?apiKey=My_API_Key&module=account&action=txlist&address=0x830dAef5E0f6D39aD689F979bb3AB468c58017FF&page=1&sort=asc&offset=1) into a browser (but with your own API key instead of My_API_Key) and copy paste the result?

Hmm that's odd.

I just released v0.5.1 of the plugin which should log the actual error that was thrown in the Etherscan request. Could you update to use v0.5.1 and try to verify again using the --debug flag. It should now display more debugging information.

how to update to latest version of truffle-plugin-verify on windows 10?

[rkalis]

I don't know a lot about windows, but I assume you have NPM installed, so you can run npm install truffle-plugin-verify@latest
