The submission and publishing interface has recently started to generate errors. The error pattern is that if there is a phased release, the error will occur in this way. If it is a full release, the error will not occur

Check if the app is in the correct state (REGISTERING) before submission. This is crucial for both phased and full releases.
Double-check the parameters being sent in the API request. Ensure that all required fields are correctly populated and that there are no missing or incorrect values.
