More pnpm-way version:

FROM node:18-slim AS web-builder
ENV PNPM_HOME="/pnpm"
ENV PATH="$PNPM_HOME:$PATH"
RUN corepack enable

WORKDIR /build
COPY invokeai/frontend/web/ ./
RUN --mount=type=cache,target=/pnpm/store \
    pnpm install --frozen-lockfile
RUN pnpm run build

Ah I see, OK thanks updated.

As per #5258 - 3.5.0 builds are still failing on rc3, this resolves the issue.
