Unable to execute `block run` without lowering security settings

I just tried following the Hello world tutorial from Airtable Blocks SDK, but I wasn’t able to go through all of it successfully.

When I invoke the block run command, I get the following error:

Error: ❌ error:140AB18F:SSL routines:SSL_CTX_use_certificate:ee key too small

It is possible to lower the default security level, but that does not seem wise.
Basically, in /etc/ssl/openssl.cnf, changing from:
CipherString = DEFAULT@SECLEVEL=2
to:
CipherString = DEFAULT@SECLEVEL=1
makes the command work.

I am running Crostini (Linux (Debian Buster) within ChromeOS), with openssl version 1.1.1d-0+deb10u3 in case that matters. The full system default section in /etc/ssl/openssl.cnf looks like:

[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT@SECLEVEL=2

This with a default install of Crostini, without me editing any configuration manually.

I am using block version 0.0.50 from the NPM package @airtable/blocks-cli.

Any chance Airtable can increase the key size somehow?
