CLI `spacetime call` cannot pass `Identity` argument for browser account linking command from website

Summary

On Windows PowerShell, the command generated by the SpacetimeDB website for linking a browser identity to a logged-in CLI identity fails with argument parsing errors.

This appears to be either:

• a Windows PowerShell quoting issue,
• a CLI parsing issue for Identity reducer arguments,
• or a mismatch between the website-generated command and the current CLI behavior.

Environment

• OS: Windows
• Shell: Windows PowerShell
• Server: Maincloud
• Auth: logged in with spacetime login

What I was trying to do

The SpacetimeDB website showed:

Web identity
c2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec

It told me to run:

spacetime call scrabblebot connect_id '["0xc2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec"]'

Then refresh the page.

Expected behavior

The website-generated command should successfully link the browser identity to the logged-in CLI identity.

Actual behavior

The command fails on Windows PowerShell.

Reproduction attempts

Attempt 1: website-generated command

spacetime call scrabblebot connect_id '["0xc2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec"]'

This was first run inside a repo directory, which caused config interference.

Attempt 2: retried outside the repo with config disabled and explicit server

spacetime call --no-config --server maincloud scrabblebot connect_id '["0xc2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec"]'

Attempt 3: tuple form with raw hex identity

spacetime call --no-config --server maincloud scrabblebot connect_id '[0xc2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec]'

Attempt 4: tuple form with string identity

spacetime call --no-config --server maincloud scrabblebot connect_id '["c2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec"]'

Notes

• The browser page displayed the identity as:

c2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec

• The page-generated command used:

["0xc2000de7bf5eeb20c27b5f117e829af4b9edf7a628d844b8f665f960fb61aaec"]

That mismatch may be relevant.

Suggestion

It would help if the website generated shell-specific commands, especially for Windows PowerShell, or documented the correct Identity argument format for spacetime call.

Start with the spacetime call CLI entry point and the argument handling for reducers with an Identity parameter. Reproduce the documented connect_id commands in Windows PowerShell and compare the website-generated format with the CLI's accepted format. Done means the browser-linking command succeeds, or the correct format and shell-specific command are documented.
