[JsonRcp] TypeError: keys must be str, int, float, bool or None, not frozendict

[Francis Hilaire]

Impacted versions: 17

Steps to reproduce:

Use Odoo Docker official image and run it with this options :

docker run -p 8069:8069 --env HOST=host.docker.internal --name odoo_17 --pull missing -t odoo:17 -- --database odoo-master-v17 --init "l10n_fr,account_accountant,sale_management"

Make an JSON-RPC call "search_read" on the model account.move.line requesting all fields.

Current behavior:

Odoo Server Error - builtins.TypeError

    return _iterencode(o, 0)
TypeError: keys must be str, int, float, bool or None, not frozendict

Expected behavior: No error

The field causing this error is compute_all_tax
