Github Action - Error: Process completed with exit code 1 - bash

Question

I am trying to setup github actions to deploy my application.
My bash-script to start the deployment process looks like this:
#!/bin/sh
set -e
vendor/bin/phpunit
(git push) || true
git checkout production
git merge master
git push origin production
git checkout master
When executing the above script I get:
My workflows/main.yml file looks like the following:
name: CD
on:
push:
branches: [ production ]
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
with:
token: ${{ secrets.PUSH_TOKEN }}
# - name: Set up Node
# uses: actions/setup-node#v1
# with:
# node-version: '12.x'
# - run: npm install
# - run: npm run production
- name: Commit built assets
run: |
git config --local user.email "action#github.com"
git config --local user.name "GitHub Action"
git checkout -B deploy
git add -f public/
git commit -m "Build front-end assets"
git push -f origin deploy
- name: Deploy to production
uses: appleboy/ssh-action#master
with:
username: root
host: xx.xx.xxx.xxx
password: ${{ secrets.SSH_PASSWORD }}
script: 'cd /var/www/myProject && ./server_deploy.sh'
When running the script I get the following raw log:

Currently nothing gets committed on my production branch, as the production action does not start.
Any suggestions what I am doing wrong?
Why do I get this error?
I really appreciate your replies!

Answer 1

Why do I get this error?
"This error", to be clear, is:
2021-03-14T16:04:29.3381472Z ##[error]Process completed with exit code 1.
The process that completed is the shell:
2021-03-14T16:04:29.0215326Z shell: /usr/bin/bash -e {0}
which ran some commands in a script; obviously one of those commands must have exited with status code 1 ("generic failure"), which led bash -e to also exit with status code 1.
We can see each command's output, so we can correlate each command to its output based on knowing what commands print what stuff. Here is the script:
git config --local user.email "action#github.com"
git config --local user.name "GitHub Action"
git checkout -B deploy
git add -f public/
git commit -m "Build front-end assets"
git push -f origin deploy
(I took out the color-changing ESC [ ... m sequences since they just get in the way, and stripped the timestamps since they're not really relevant.) You should recognize these commands: they are the ones you supplied in your YAML file.
Here is the output from each of those commands:
Switched to a new branch 'deploy'
On branch deploy
nothing to commit, working tree clean
Now, git config normally prints nothing, so the two git configs probably succeeded because we saw something printed (the first line). What we saw printed was Switched to a new branch 'deploy'.
This is exactly what the third command, git checkout -B deploy, would print when it succeeds. So we must have reached the third command, which succeeded. That would let us move on to the fourth command, git add -f public/.
The git add command normally prints nothing. So we can't really be sure if it worked or not at this point, but we do see further output, beginning with On branch .... That definitely doesn't come from git add, so presumably git add succeeded, which would let us move on to the fifth command, git commit -m [message]. This command does print things, on both success and failure: on success we get a message showing the new commit's abbreviated hash ID, and on failure, we get git status output:
$ git status
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
$ git commit -m test
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
This is, in fact, a failure of sorts: there is nothing to commit, so Git does not make a new commit. Why is there nothing to commit? Because Git's index matches the current (HEAD) commit. That is, git add -f public/ updated no files. Either public/ is empty, or the files inside public/ match those in the HEAD commit.
If we check the actual exit status from a git commit that fails in this way, it is 1:
$ echo $?
1
So the git commit command is the one that failed, and it failed because there was nothing new to commit.
You have multiple choices for how to proceed:
Figure out why there was nothing to commit, when you clearly expected there to be something to commit.
Check whether there is anything to commit, and if not, commit nothing.
Use git commit --allow-empty to instruct Git to make a new commit even if there's no need for a new commit. (This has the advantage of being extremely simple.)
Forcibly assume that the git commit succeeds even when it fails, by using the (cmd || true) construct, just as you did here:
(git push) || true
I put these in approximate order of increasing badness, though some of this is a matter of opinion / judgment.
Note that when diagnosing some script's failure, there are several approaches that can help if it's not immediately obvious which command within the script failed. For instance, here, it was clear that git commit failed, because only git commit winds up acting like git status, and it does that precisely when it's going to fail with a "nothing to commit" message. But what if it were some other, more-ambiguous failure? One can narrow down these failures by adding echo commands, so that we know which part(s) of the script are running. Or, if it doesn't interfere too much with other things, we can set -x in a bash script: this causes the shell to print out, to standard error output, a + line for each command it actually runs, just before running it. This would immediately pin the exit status to the command that produced it.
