can't create-invite-code bc pds_email error

[irenetherogue]

I'm trying to setup a bsky instance on DigitalOcean but they're convinced the issue is that i'm trying to send emails from the droplet.

I'm following this walkthru, from Sept 2024:
https://rafaeleyng.github.io/self-hosting-a-bluesky-pds-and-using-your-domain-as-your-handle

I've made it to configuring SMTP on the PDS and entered the code the walkthru gave:

echo 'PDS_EMAIL_SMTP_URL=smtps://resend:[email protected]:465/' >> /pds/pds.env
echo 'PDS_EMAIL_FROM_ADDRESS=[email protected]' >> /pds/pds.env
reboot

but no matter what i do, when i enter "pdsadmin create-invite-code" it spits out this error:

/pds/pds.env line 16 pds_email: command not found

In case it matters, I'm also using Resend and Namecheap, as the walkthru recommends
I admittedly am not very skilled at this yet, and suspect it's a simple fix but I haven't seen anyone else report this issue yet

Tysm for reading, and for any help you can give :)
