Running Lago's single Docker image (v1.25.0 and 1.24.1) via docker run --rm -it --name lago -p 80:80 -p 3000:3000 getlago/lago:v1.25.0, clicking Integrations > Stripe and entering a Stripe test secret key produced the UI toast 'An error occured, please restart the application' plus an API 500. The logs showed a Segment-related error. The same Stripe keys worked fine on the Docker Compose deployment, so it was specific to the one-click image.
