Hi! I tried different things to make it works with version 1.19.0 and it did not work when I upgrade the version to 1.22.1. First of all, I created github repository for the transform, the model and the dbt. I install custom extractor by doing this command: ```meltano add --custom extractor tap-github``` (namespace): tap_github (pip_url): tap-github==1.5.0 or git+https://github.com/L3houx/tap-github.git (executable) [tap-postgres]: tap-github (capabilities): discover,properties,state This is my meltano.yml file. I added settings to the extractor to use env variables. I also added a custom transform and model. ``` plugins: dashboards: - name: dashboard-google-analytics pip_url: git+https://gitlab.com/meltano/dashboard-google-analytics.git extractors: - capabilities: - discover - properties - state executable: tap-github name: tap-github namespace: tap_github pip_url: git+https://github.com/L3houx/tap-github.git settings: - env: GITHUB_A_T name: access_token - env: GITHUB_REPO name: repository - label: GitLab name: tap-gitlab pip_url: git+https://gitlab.com/meltano/tap-gitlab.git - label: Google Analytics name: tap-google-analytics pip_url: git+https://gitlab.com/meltano/tap-google-analytics.git loaders: - label: PostgreSQL name: target-postgres pip_url: git+https://github.com/meltano/target-postgres.git models: - name: model-github pip_url: git+https://github.com/L3houx/model-github.git - name: model-gitlab pip_url: git+https://gitlab.com/meltano/model-gitlab.git - name: model-google-analytics pip_url: git+https://gitlab.com/meltano/model-google-analytics.git orchestrators: - name: airflow pip_url: apache-airflow==1.10.2 transformers: - name: dbt pip_url: dbt==0.14.4 transforms: - name: tap-github pip_url: https://github.com/L3houx/test-dbt-tap-github.git vars: schema: '{{ env_var(''MELTANO_LOAD_SCHEMA'') }}' - name: tap-gitlab pip_url: https://gitlab.com/meltano/dbt-tap-gitlab.git vars: schema: '{{ env_var(''MELTANO_LOAD_SCHEMA'') }}' ultimate_license: '{{ env_var(''GITLAB_API_ULTIMATE_LICENSE'', False) }}' - name: tap-google-analytics pip_url: https://gitlab.com/meltano/dbt-tap-google-analytics.git vars: schema: '{{ env_var(''MELTANO_LOAD_SCHEMA'') }}' project_id: 3bd1afa6-b687-4b12-8b8d-595c547b1215 send_anonymous_usage_stats: true version: 1 ``` After that, I tried to do : * meltano add transform tap-github * meltano add model model-github * meltano install and nothing works. So I tried to had the section into discovery.yml. So I added this to discovery.yml in the transforms section: ``` - name: tap-github namespace: tap_github pip_url: 'https://github.com/L3houx/test-dbt-tap-github.git' vars: schema: "{{ env_var('MELTANO_LOAD_SCHEMA') }}" ``` I added this to discovery.yml in the models section: ``` - name: model-github namespace: tap_github pip_url: git+https://github.com/L3houx/model-github.git ``` After I did the same 3 commandes: * meltano add transform tap-github * meltano add model model-github * meltano install The custom transform and model installed and it worked when I get data from a github repsitory. The problem came when I upgrade meltano's version with the command: `meltano upgrade`. Its uninstalled the transform and the model and every time I tried to add sections to discovery, it is reloading to the original version and erase all the modification I made. I also tried: `meltano add --custom transform tap-github` and this is the error I got:  I would like to know how to properly add a custom transform and model. Thank you and have a nice day!
