export specific secret value as an environment variable

Hey @Nadros, thank you for reaching out to us!
Quick question, before diving deeper into troubleshooting this: Have you tried the op read command? By glancing through the thread, I think this may actually be a simpler way to achieve the same result. The syntax would be: op read op://<vault-name>/<item-name>/<field-name>.
More documentation can be found at https://developer.1password.com/docs/cli/reference/commands/read/
Let us know if this helps you!
Looking forward to hearing from you.

Best,
Horia
