Tai An 53006bb8e1 fix(realtime): accept legacy 'modalities' alias for output_modalities (fixes #11103) (#11104)
* fix(realtime): accept legacy 'modalities' alias for output_modalities

OpenAI's Realtime *beta* used the field name `modalities`; the GA field is
`output_modalities`. LocalAI only binds `output_modalities`, so a client
sending the still-common beta field `modalities: ["text"]` has it silently
dropped by encoding/json and the session falls back to audio: TTS runs and the
client receives large response.output_audio.* frames even though it asked for
text-only.

Accept `modalities` as an alias on both session.update (RealtimeSession) and
response.create (ResponseCreateParams). The GA `output_modalities` wins when
both are present, so GA clients are unaffected. Applied at the two existing
resolution points via a small modalitiesWithAlias helper.

Fixes #11103

* test(realtime): add JSON-boundary regression for modalities alias

Decode representative session.update and response.create payloads that
carry only the legacy beta `modalities` key and assert the effective
output modality resolves to text (not audio), reproducing the exact
expressions used in updateSession and triggerResponseAtTurn. This guards
against a wrong JSON tag or a missed call site letting encoding/json drop
the alias silently.

Also document output_modalities (and the accepted legacy modalities
alias) for text-only sessions in the realtime feature docs.

Requirement

In this project, the Docsy theme component is pulled in as a Hugo module, together with other module dependencies:

$ hugo mod graph
hugo: collected modules in 566 ms

If you want to do SCSS edits and want to publish these, you need to install PostCSS

npm install

Running the website locally

Building and running the site locally requires a recent extended version of Hugo. You can find out more about how to install Hugo for your environment in our Getting started guide.

Once you've made your working copy of the site repo, from the repo root folder, run:

hugo server

Running a container locally

You can run docsy-example inside a Docker container, the container runs with a volume bound to the docsy-example folder. This approach doesn't require you to install any dependencies other than Docker Desktop on Windows and Mac, and Docker Compose on Linux.

  1. Build the docker image

    docker-compose build
    
  2. Run the built image

    docker-compose up
    

    NOTE: You can run both commands at once with docker-compose up --build.

  3. Verify that the service is working.

    Open your web browser and type http://localhost:1313 in your navigation bar, This opens a local instance of the docsy-example homepage. You can now make changes to the docsy example and those changes will immediately show up in your browser after you save.

Cleanup

To stop Docker Compose, on your terminal window, press Ctrl + C.

To remove the produced images run:

docker-compose rm

For more information see the Docker Compose documentation.

Troubleshooting

As you run the website locally, you may run into the following error:

➜ hugo server

INFO 2021/01/21 21:07:55 Using config file: 
Building sites … INFO 2021/01/21 21:07:55 syncing static files to /
Built in 288 ms
Error: Error building site: TOCSS: failed to transform "scss/main.scss" (text/x-scss): resource "scss/scss/main.scss_9fadf33d895a46083cdd64396b57ef68" not found in file cache

This error occurs if you have not installed the extended version of Hugo. See this section of the user guide for instructions on how to install Hugo.

Or you may encounter the following error:

➜ hugo server

Error: failed to download modules: binary with name "go" not found

This error occurs if you have not installed the go programming language on your system. See this section of the user guide for instructions on how to install go.
