```

I have checked the named values folder of the extracted files and I can find the folder with the same name the log is saying don't find it and the content is similar to this one:

```
{
"properties": {
"displayName": "func-xxx-xxxx-xxxx-xxx-xxxx-key",
"secret": true,
"tags": [
"key",
"function",
"auto"
]
}
}
```
And of course I can find that name value on the original APi Management.

Our Azure Functions are being imported in API Management using the wizard, that's why there is a tag "auto"

I'm wondering if this is happening due to the way we are importing our Azure Functions on API Management or because the named values are secrets.

### Expected behavior

Expected successful publishing

### Actual behavior

{"error":{"code":"ValidationError","message":"One or more fields contain incorrect values:","details":[{"code":"ValidationError","target":"credentials","message":"Property 'func-xxx-xxxx-xxxx-xxx-xxxx-key' not found."}]}}

### Reproduction Steps

Execute run-publisher-with-env.yaml
