How to disable --auto-truncate via the `text-embeddings-router` CLI?

• Docker
• The CLI directly

Tasks

• An officially supported command
• My own modifications

Reproduction

The README states that the text-embeddings-router CLI provides the --auto-truncate parameter, set to true by default. I would like to disable automatic truncation by the server but can't seem to do it:

$ text-embeddings-router --auto-truncate false --model-id foo
# error: unexpected argument 'false' found
# 
# Usage: text-embeddings-router [OPTIONS] --model-id <MODEL_ID>
# 
# For more information, try '--help'.

I tried a bunch of other idiomatic CLI formats for boolean flags (e.g. --no-auto-truncate, --auto-truncate off, --auto-truncate 0) but none worked. Setting the envvar AUTO_TRUNCATE=false does the job, but it's awkward to have to mix CLI parameters and environment variables.

How can I configure the --auto-truncate setting via the command-line?

Expected behavior

I would have expected --auto-truncate {true,false} to work.

Thanks for raising this @slavistan.
#836 should fix this.
