v1.44.0 gRPC client support doesn't work

[rnbguy]

Version: Deno v1.44.0

I opened this issue because of this comment: #3326 (comment)

We have a NPM executable that connects to a gRPC server. The current gRPC support doesn't work with it.

You can reproduce this by doing the following:

git clone https://github.com/informalsystems/quint
cd quint/examples/cosmos/ics20
deno run -A npm:@informalsystems/quint verify --max-steps=3 --main=bankTests --invariant=BalanceNonNegative,NonExistantAccountsOrCoinsAreZero bank.qnt

I get the following error:

Warning: Not implemented: Http2Session.socket
Warning: Not implemented: Http2Session.socket

Internally, @informalsystems/quint downloads apalache and executes apalache server that launchs the gRPC server and then quint tries to connect to it via @grpc/grpc-js.

The source code for the gRPC client lives at https://github.com/informalsystems/quint/blob/main/quint/src/apalache.ts.

Am I doing anything wrong?

PS. to minimize the debugging overhead, you can just use apalache and this Deno script: https://gist.github.com/rnbguy/77e73b3ea9515f8013a66060acb9796f.

In two different terminals:

apalache server

deno run ping_apalache.ts
