Upgrading snaps-cli to 0.31 gives checksum mismatch error

[tmpfs]

After upgrading @metamask/snaps-cli from 0.27.1 to 0.31.0 I get this error when trying to install/connect to the snap (using Flask 10.26.1):

{
    "code": -32603,
    "message": "Failed to fetch Snap \"local:http://localhost:7070/\": Invalid Snap manifest: manifest shasum does not match computed shasum..",
    "data": {
        "originalError": {}
    }
}

No errors are given building using snaps-cli and the manifest looks like this:

{
  "version": "0.2.0",
  "description": "Snap using threshold signatures to sign messages and transactions.",
  "proposedName": "Threshold Signatures",
  "repository": {
    "type": "git",
    "url": "https://github.com/LavaMoat/tss-snap"
  },
  "source": {
    "shasum": "6eELF6Z5UV8ypUeI9P9HadxswDp4BUCi00nGSDg+CkE=",
    "location": {
      "npm": {
        "filePath": "bundle.js",
        "iconPath": "images/icon.svg",
        "packageName": "@lavamoat/tss-snap",
        "registry": "https://registry.npmjs.org/"
      }
    }
  },
  "initialPermissions": {
    "snap_manageState": {},
    "endowment:rpc": {
      "dapps": true,
      "snaps": false
    }
  },
  "manifestVersion": "0.1"
}

I tried removing the snap first and that didn't help.

Any ideas what I need to do to get this working again please?

For now I will downgrade.

The currently released Flask version is not compatible with 0.31.0. If you want to use the latest packages you need to build from the extension develop. An upcoming Flask version will bring support for 0.31.0.

Thanks @FrederikBolding, going to close this then.

@FrederikBolding is 31 released now? I installed Flask today, and it says it's 10.31.0-flask.0 - is that the same as 0.31.0?

Could this be causing ChainSafe/filsnap#258 ?

[FrederikBolding]

@vorburger 0.31.0 has been released yes. Unfortunately there is not a 1:1 mapping between the Flask version and the version of the Snaps packages. But to support 10.31.0-flask.0 a snap must be built with minimum Snaps CLI version 0.30.0 (0.31.0 and onwards is also fine!)

[vorburger]

@FrederikBolding ACK, thanks. FYI and just FTR for future readers, in ChainSafe/filsnap#260 I have meanwhile rebuilt the shasum for filsnap with the latest (current) Snaps CLI in order to fix ChainSafe/filsnap#258.
