Issue: Auto Approve Not Working in PR Agent

[PoMaH07]

Summary

The auto-approve feature of PR Agent is not functioning as expected despite being configured in the .pr_agent.toml file and executed through GitLab CI. The main goal is to enable auto-approval based on predefined criteria.

---

Steps to Reproduce

1. Set up the .pr_agent.toml file with the following configuration:

   [pr_reviewer]
   require_tests_review = true
   require_security_review = true
   require_estimate_effort_to_review = true
   ask_and_reflect = false
   final_update_message = true
   require_score_review = false
   
   persistent_comment = false
   inline_code_comments = false
   enable_review_labels_effort = true
   enable_review_labels_security = true
   enable_auto_approval = true
   
   [pr_code_suggestions]
   demand_code_suggestions_self_review = true
   approve_pr_on_self_review = true
   focus_only_on_problems = true
   commitable_code_suggestions = true
   apply_suggestions_checkbox = true
   summarize = true

2. Place the .pr_agent.toml file in the develop branch of the repository.
3. Execute the GitLab CI pipeline with the following job configuration:

   pr_agent_job:
     stage: pr_agent
     image:
       name: codiumai/pr-agent:latest
       entrypoint: [""]
     script:
       - cd /app
       - echo "Running PR Agent action step"
       - export MR_URL="$CI_MERGE_REQUEST_PROJECT_URL/merge_requests/$CI_MERGE_REQUEST_IID"
       - echo "MR_URL=$MR_URL"
       - export gitlab__url=$CI_SERVER_PROTOCOL://$CI_SERVER_FQDN
       - export gitlab__PERSONAL_ACCESS_TOKEN=$GITLAB_PERSONAL_ACCESS_TOKEN
       - export config__git_provider="gitlab"
       - export openai__key=$OPENAI_KEY
       - python -m pr_agent.cli --pr_url="$MR_URL" describe
       - python -m pr_agent.cli --pr_url="$MR_URL" review auto_approve --pr_reviewer.require_score_review=true --pr_reviewer.enable_review_labels_effort=true --pr_reviewer.require_security_review=true --best_practices.enable_global_best_practices=true
       - python -m pr_agent.cli --pr_url="$MR_URL" improve --config.output_relevant_configurations=true

4. Observe the logs and behavior of the PR Agent.

Observed Behavior

1. The following log message indicates that the auto-approval feature is disabled:

   2025-01-23 14:26:15.765 | INFO     | pr_agent.tools.pr_reviewer:run:126 - Auto approve flow PR: https://gitlab ...
   2025-01-23 14:26:15.767 | INFO     | pr_agent.tools.pr_reviewer:auto_approve_logic:410 - Auto-approval option is disabled
   

2. The approve_pr_on_self_review setting does not approve the PR even when the checkbox "I am familiar with the suggestions" is selected.
3. The apply_suggestions_checkbox setting does not add the expected checkbox for applying suggestions.
4. The commitable_code_suggestions setting works correctly, allowing immediate commits of suggestions.
5. The --config.output_relevant_configurations=true flag does not output the configuration applied during the improve step.

---

Expected Behavior

1. The auto-approval feature should work when enable_auto_approval = true is set in .pr_agent.toml.
2. The approve_pr_on_self_review setting should approve the PR when the self-review checkbox is selected.
3. The apply_suggestions_checkbox setting should add the expected checkbox in the interface.
4. The --config.output_relevant_configurations=true flag should output the effective configuration applied during the process.

---

Additional Context

• The .pr_agent.toml file is located in the develop branch of the repository.
• The team uses GitLab as the primary Git provider.

Request for Assistance

Please advise on:

1. Why the enable_auto_approval setting is not being respected despite being set to true.
2. Any additional steps or configurations required to enable auto-approval functionality.
3. Debugging steps to determine why specific settings (e.g., approve_pr_on_self_review, apply_suggestions_checkbox) are not functioning as expected.
4. How to ensure that --config.output_relevant_configurations=true outputs the correct configuration during the CI pipeline run.
