| # HTTPS landing-page fix · 2026-10-14 | |
| The deployed root returned HTTP 307 with an absolute `http://` Location even | |
| when requested over HTTPS. HF terminates TLS before forwarding requests to | |
| Python; `request.url` can therefore report HTTP. The old middleware copied | |
| that internal scheme into the browser-facing redirect. This is an actual | |
| deployment defect and can block the page inside the HTTPS HF iframe. | |
| `workflow_ui.py` now returns a relative `/?ui=canvas` redirect, preserving | |
| existing query parameters and the browser's HTTPS origin. The redirect uses | |
| `Cache-Control: no-store`. This is the only production-code change in this | |
| startup fix; inference code and dependencies remain unchanged. | |
| Validation: | |
| - 40 tests and 6 subtests pass, including an HTTP proxy-scope regression that | |
| checks resolution of the relative Location against the HTTPS browser URL. | |
| - A real local Gradio 6.30.0 process follows the redirect to HTTP 200 canvas | |
| HTML, resolves its configured canvas ID through `component_server`, and | |
| completes upload, queued Prepare Source, anchor serving and point saving. | |
| - The existing deployed `https://fffiloni-viggle-mine-workflow.hf.space/?ui=canvas` | |
| rendered the actual empty graph in the browser at 100% and fit-to-view 32%. | |
| This direct URL avoids the defective root redirect. It is not validation of | |
| the corrected build inside the HF iframe, nor of inference or mobile use. | |
| The reported `KeyError: 142` means a component-server request referenced an ID | |
| absent from the serving Blocks registry. In the inspected live config the | |
| canvas ID was 1; its read-only `get_workflow_key` request returned HTTP 200. | |
| That does not prove the user's request was caused by a stale cache. The | |
| original failing request was not reproduced, and this patch must not be | |
| described as a demonstrated fix for that exception. Do not remap unknown IDs | |
| or suppress the exception as a substitute for identifying the mismatch. | |
| Deploy the updated consolidated archive, or replace only `workflow_ui.py` | |
| for the runtime fix. Then verify the embedded HF page and root redirect in | |
| the new deployment. No remote deployment was performed by this repair. | |
| ## Subsequent construction repair | |
| The consolidated execution repair additionally removes two lifecycle defects: | |
| `with demo` during GPU function registration reran canvas load-event attachment, | |
| and `create_app` followed by `launch(_app=...)` installed the native route and | |
| middleware stack twice. Registration now uses Gradio 6.30's `_active_blocks` | |
| helper, and the custom App receives native setup only in launch. A construction | |
| regression checks both the registration branch and live component registry. | |
| The complete suite is now 49 tests plus 6 subtests; the earlier counts above | |
| refer to the preceding HTTPS-only repair. Use the full consolidated package; | |
| replacing only workflow_ui.py is no longer the complete repair. | |
