Flow Wallet Minimal Error Reproduction

Background

I am getting a Frame Send Error when trying to authenticate with FCL on the emulator, using the emulator wallet. I'm using flow CLI v0.37.0.

Steps to reproduce

1. Install flow CLI version 0.37.0
2. Run flow emulator --contracts
3. Run flow dev-wallet -f wallet_flow.json --emulator-host http://localhost:8888
4. Run yarn dev

Navigate to http://localhost:3000 and open the browser console. You should see the following error:

Frame Send Error {type: 'FCL:VIEW:READY:RESPONSE', fclVersion: '1.1.0', body: {…}, service: {…}, config: {…}}body: {data: undefined}data: undefined[[Prototype]]: Objectconfig: {discoveryAuthnInclude: Array(0), services: {…}, app: {…}, client: {…}}fclVersion: "1.1.0"service: {params: undefined, data: undefined, type: 'authn'}type: "FCL:VIEW:READY:RESPONSE"[[Prototype]]: Object TypeError: Cannot read properties of undefined (reading 'postMessage')

    at onReady (fcl.module.js?6838:1117:1)

Resolution

This has been resolved by upgrading the Flow CLI to v0.37.2
