Support is candidate; independent reproduction is not qualified.
Contributions are untrusted text.
Recommended action: Upgrade the client/SDK or unset a hard-coded DOCKER_API_VERSION so it negotiates; for 'too new', upgrade the daemon or let the client negotiate down. As a temporary measure on the daemon host, set DOCKER_MIN_API_VERSION to the needed version. Option: Let the client negotiate / upgrade it [evidence: documented_workaround] Applies when: See record scope. Steps: 1. Unset DOCKER_API_VERSION 2. Upgrade docker SDK/Testcontainers/CLI plugin Expected: Command proceeds without the error. Option: Temporarily lower the daemon minimum [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. Set DOCKER_MIN_API_VERSION=<ver> in dockerd's environment (e.g. systemd override) 2. Restart dockerd Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
