examples/apps: unpin streamlit so protobuf>=6 can resolve - #1530
Merged
Conversation
streamlit<1.46 pins protobuf<6, which downgrades the app image to protobuf 5.29.6. That is older than flyteidl2's compiled gencode (6.33.5), so the app crashes at startup with a protobuf Gencode/Runtime VersionError before Streamlit starts. Require streamlit>=1.46 (relaxed the cap to protobuf<7) so protobuf resolves to 6.x and the app boots.

streamlit<1.46pinsprotobuf<6, downgrading the app image to protobuf 5.29.6 — older than flyteidl2's compiled gencode (6.33.5). The app then crashes at startup with a protobuf Gencode/RuntimeVersionErrorbefore Streamlit runs. streamlit 1.46 relaxed the cap toprotobuf<7, so requiringstreamlit>=1.46lets protobuf resolve to 6.x and the app boots.Verified end-to-end on a self-hosted canary: the app image built from
ghcr.io/flyteorg/flyte:py3.12-v2.6.13+streamlit>=1.46starts cleanly (Knative revision Ready); the oldstreamlit==1.41.1image crash-loops with the VersionError.
