None found for this typing gap with defineJsonSecret and secrets arrays.

[REQUIRED] Version info

node: node --version (v24.11.1)

firebase-functions: from package.json (7.0.0)

firebase-tools: firebase --version (14.26.0)

firebase-admin: from package.json (13.6.0)

[REQUIRED] Test case

import { defineJsonSecret, onRequest } from 'firebase-functions/https'; interface Config { foo: string; } const jsonSecret = defineJsonSecret<Config>('JSON_SECRET'); export const test = onRequest( { secrets: [jsonSecret] }, // TS error here (_req, res) => { res.json({ foo: jsonSecret.value().foo }); } );

[REQUIRED] Steps to reproduce

1. Install firebase-functions v7.0.0.
2. Define a JSON secret with defineJsonSecret.
3. Pass the resulting JsonSecretParam into the secrets array of a function.
4. Compile with TypeScript.

[REQUIRED] Expected behavior

TypeScript accepts JsonSecretParam in secrets (just like SecretParam or a string name), since JSON secrets are supported at runtime.

[REQUIRED] Actual behavior

TypeScript error:

Type 'JsonSecretParam<Config>' is not assignable to type 'string | SecretParam'. Type 'JsonSecretParam<Config>' is not assignable to type 'SecretParam'. The types returned by 'value()' are incompatible between these types. Type 'Config' is not assignable to type 'string'. 

SDK typings show secrets?: (string | SecretParam)[]; across options. JsonSecretParam is defined in params/types, but not accepted by secrets. Runtime converters also only check instanceof SecretParam.

Were you able to successfully deploy your functions?

This is a compile time issue, I did not attempt to deploy.
