start_lexical.sh exiting early when no version manager is installed

[JonasGruenwald]

I'm using the vscode extension, and I have verified that it has installed the latest version of lexical ("0.5.0").

The vscode extension fails to start up since it's trying to run start_lexical.sh which exits with exit code 1.
I have looked into start_lexical.sh and activate_version_manager.sh and I have found that

• Since I have none of these version managers installed (I installed Elixir via homebrew) it goes through the whole activate_version_manager.sh, printing "No activated version manager detected. Searching for version manager..." and exits with exit code 1 at the end after trying mise
• At this point, I believe start_lexical.sh should print "Could not activate a version manager. Trying system installation." and continue to start lexical, but instead the script just exits with code 1 without printing anything.

From what I can tell this is happening because of set -e at the start of start_lexical.sh, if I change the second line to just set -o pipefail instead of set -eo pipefail the script works as expected for me.

I have to say I'm not sure why because from what I understand set -e shouldn't cause an exit if the non-zero exiting command is called in an if-statement, which it is, but it does happen 🤷
For context I am on MacOS and my bash version is
