Pseudolocale Add-On fails to create

[sakachi99]

Describe the issue

After upgrading to Weblate 5.4.1.1 (and now 5.4.2.1) we can no longer setup the pseudolocale plugin on a component housed inside a project and pressing "Save". We receive an error message. TypeError: Object of type Translation is not JSON serializable

I already tried

• [X] I've read and searched the documentation.
• [X] I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

• Make a component in a project
• In settings: Add-On, add the Pseudolocale add-on
• Configure the source strings and target translation (en and en-XA, in my case)
• Click save

Expected behavior

The target translation should now be filled in where the source strings get pseudolocalled? ie. "hallo" -> "$_____hallo_____$"

Weblate deploy checks

SystemCheckError: System check identified some issues:

CRITICALS:
?: (weblate.E027) The path /app/data/weblateSettingsFull.py is owned by a different user, check your DATA_DIR settings.
        HINT: https://docs.weblate.org/en/weblate-5.4.2/admin/install.html#file-permissions

WARNINGS:
?: (security.W004) You have not set a value for the SECURE_HSTS_SECONDS setting. If your entire site is served only over SSL, you may want to consider setting a value and enabling HTTP Strict Transport Security. Be sure to read the documentation first; enabling HSTS carelessly can cause serious, irreversible problems.
?: (security.W008) Your SECURE_SSL_REDIRECT setting is not set to True. Unless your site should be available over both SSL and non-SSL connections, you may want to either set this setting True or configure a load balancer or reverse-proxy server to redirect all connections to HTTPS.
?: (security.W012) SESSION_COOKIE_SECURE is not set to True. Using a secure-only session cookie makes it more difficult for network traffic sniffers to hijack user sessions.
?: (security.W018) You should not have DEBUG set to True in deployment.

Additional context

We are not running a deployed production instance, only a locally served test instance.

We successfully added the pseudolocale to components in Weblate 4.14, We cannot add it since upgrading to 5.4.1.1 and 5.4.2.
