Expected Behaviour

A feature succesfully being added in app configuration with name 'my/feature' and with key '.appconfig.featureflag/my/test'.

Actual Behaviour

The feature is added, but terraform is failing with an error after creation. State is also 'corrupted', meaning I cannot fix it by changing my feature configuration. (for example by changing the slash into a dash)

Steps to Reproduce

1. setup app configuration as described in the documentation: https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/app_configuration_feature
2. add a slash in the name
3. execute terraform plan -> no errors
4. execute terraform apply -> fails with an error (feature is created in azure app configuration)
5. remove the slash from the name
6. execute terraforn plan -> fails with the same error

Important Factoids

No response

References

A fix was done here #16835 but the focus was on the labels if I'm not mistaken?
A fix for supporting the slash in keys was done here: #13852

Both fixed were done for azurerm_app_configuration_key but should also be executed for azurerm_app_configuration_feature?

Hi @fgroen, thanks for opening this issue.

Sorry the provider does not support name with slashes in azurerm_app_configuration_feature, a pr (#19470) has been submitted to fix this bug.

to fix the state file. Here are 2 options to fix the state file.

---

1. If it's acceptable to wait for the fix pr merged and released, please wait for it and then it will automatically fix the state file without resources deletion.

---

2. If it's not acceptable to wait, please delete the feature by Portal or azcli and then run

terraform state rm 'azurerm_app_configuration_feature.feature_toggle'   

to delete it from state file.

---

For any further question please leave comments, thank you!
