### Answer I don't have information in the available sources that specifically addresses this 400 error about "additional properties" in the staging environment tag configuration. However, based on the documentation, here are the tag name requirements that might be relevant: [(1) ]() - Up to 20 characters - May contain lowercase letters, numbers,

-

, or

_

- Must start with a lowercase letter - Cannot be

latest

- Cannot match the pattern

v

followed by numbers only (e.g.

v3

,

v12

) The error suggests there may be extra properties in your staging tag configuration that aren't expected by the API. When configuring environment tags, you should only define environment dynamic variables (key/value pairs) within the tag settings. If you're still experiencing issues, I'd recommend: - Visit [Documentation]() - Visit [Hire certified Retell partner]() Would you like a general answer based on my knowledge instead?

### Answer I don't have specific information in the available sources about how to submit bug reports to Retell AI support directly. For technical support and assistance with potential bugs, I recommend: - Visit [Documentation]() - Visit [Hire certified Retell partner]() The 400 error you're experiencing with "must NOT have additional properties" suggests the API is receiving unexpected fields in the staging tag configuration. The tag name requirements are correct [(1) ]() , but the error indicates there may be additional properties being sent in the request body that the API doesn't expect. When configuring environment tags, each tag should only contain environment dynamic variables as key/value pairs . Double-check that you're not including any extra fields or properties beyond what's documented in the tag configuration. Would you like me to provide a general answer based on my knowledge about potential workarounds?
