Checklist

• I have read and understood the rules about how to Contribute to this project
• The pull request is for the branch develop
• A new plugin (analyzer, connector, visualizer, playbook, pivot or ingestor) was added or changed, in which case:
  • I strictly followed the documentation "How to create a Plugin"
  • Usage file was updated.
  • Advanced-Usage was updated (in case the plugin provides additional optional configuration).
  • I have dumped the configuration from Django Admin using the dumpplugin command and added it in the project as a data migration. ("How to share a plugin with the community")
  • If a File analyzer was added and it supports a mimetype which is not already supported, you added a sample of that type inside the archive test_files.zip and you added the default tests for that mimetype in test_classes.py.
  • If you created a new analyzer and it is free (does not require any API key), please add it in the FREE_TO_USE_ANALYZERS playbook by following this guide.
  • Check if it could make sense to add that analyzer/connector to other freely available playbooks.
  • I have provided the resulting raw JSON of a finished analysis and a screenshot of the results.
  • If the plugin interacts with an external service, I have created an attribute called precisely url that contains this information. This is required for Health Checks.
  • If the plugin requires mocked testing, _monkeypatch() was used in its class to apply the necessary decorators.
  • I have added that raw JSON sample to the MockUpResponse of the _monkeypatch() method. This serves us to provide a valid sample for testing.
• If external libraries/packages with restrictive licenses were used, they were added in the Legal Notice section.
• Linters (Black, Flake, Isort) gave 0 errors. If you have correctly installed pre-commit, it does these checks and adjustments on your behalf.
• I have added tests for the feature/bug I solved (see tests folder). All the tests (new and old ones) gave 0 errors.
• If changes were made to an existing model/serializer/view, the docs were updated and regenerated (check CONTRIBUTE.md).
• If the GUI has been modified:
  • I have a provided a screenshot of the result in the PR.
  • I have created new frontend tests for the new component or updated existing ones.
• After you had submitted the PR, if DeepSource, Django Doctors or other third-party linters have triggered any alerts during the CI checks, I have solved those alerts.

Important Rules

• If you miss to compile the Checklist properly, your PR won't be reviewed by the maintainers.
• Everytime you make changes to the PR and you think the work is done, you should explicitly ask for a review. After being reviewed and received a "change request", you should explicitly ask for a review again once you have made the requested changes.

Probably I did something wrong, however I suggest to add some logs and make the error more verbose to help the user/develop to better understand the reason why the config is not correct and the analyzer doesn't work.

I noticed 3 things:

• A little bug in the alignment of the buttons
  
• An error in the validation: if you put some spaces in the analyzer name the field is marked in green but an error is raised when the "save" button is pressed
  
• If you want to use the observable name in the url http://example.com/<observable> you have to delete the param to avoid to appen them as get param. But if you delete everything it is auto populated again, you have to insert {}, this could be a problem from a UX perspective
