Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.66.0
• OS Version: MacOS 11.5.2

Steps to Reproduce:

1. brew install bash-git-prompt
2. Add the relevant lines to ~/.bash_profile to enable the prompt

if [ -f "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh" ]; then
  __GIT_PROMPT_DIR=$(brew --prefix)/opt/bash-git-prompt/share
  GIT_PROMPT_ONLY_IN_REPO=1
  source "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh"
fi

3. Verify it works in regular OS terminal (outside VSCode or inside VSCode without experimental shell integration)

4. Enable the experimental shell integration in VSCode
5. Using the integrated terminal, visit the same location and see the error
