Do you have a clue of how to fix it ? I didn’t click on Login button to get this error …

I tried to install social-auth-core==4.3.0 within the Dockerfile, but I don’t know exactly why, but it upgrades my nautobot to 1.4.x too … So I rollback to my previous Dockerfile and exec the pip install social-auth-core==4.3.0 command when my container was up, and it’s a success, it fix the issue.

I’ll try to upgrade to nautobot 1.4 so.

Just for reference, if we use a OIDC server with self certificate SSL or with custom CA, you need to import your CA in the nautobot container like this : in Dockerfile :

COPY yourCA.pem /usr/local/share/ca-certificates/yourCA.crt
USER root
RUN update-ca-certificates
ENV REQUESTS_CA_BUNDLE "/etc/ssl/certs/ca-certificates.crt"
USER nautobot

Closing issue as this is fixed in a newer release.
