Use ethers JS failed to generate Wallet
2022-02-03 20:54:17 【Q & A of Denglian community】
TypeError: Cannot read property 'sendTransaction' of undefined
The reason for the error is that the wallet... Was not generated , But I seem to have generated a wallet . My backstage is koa. When I start the background, I directly use the private key to generate a wallet
I put contract、provider、manager After export , At the project entrance file index.js Put into global variables
Then I'm using manager That's when the wallet , It happened. underfined error . I printed these three variables before the error , Find out contract and provider It's normal , however manager It becomes underfined. I don't understand what went wrong .
All other interactions with Ethereum are OK . For example, use an account with balance to write something into the smart contract .
Take the answer 1：
Probably yours provider Not connected .
You still need to debug yourself .
