@kapa.ai I’m upgrading to use Airbyte 0.50.24 and Snowflake Destinations v2 (version 3.2.3); but I get this error when I reset streams
Copy code
Failure reason: Failed to detect if there is a schema change. If the error persist please contact the support team.

Hmm, I don't know enough to give you a confident answer yet. However, I can guide you on how to handle schema changes and errors based on the information I have. When you encounter an error during schema changes, it's important to review the changes and fix them. If the error is due to a breaking change, you might need to upgrade your source or destination to a new version to continue syncing. If a connection’s source schema has breaking changes, it will stop syncing immediately. You must review and fix the changes before editing the connection or resuming syncs [source](https://docs.airbyte.com/cloud/managing-airbyte-cloud/manage-schema-changes). In addition to Airbyte Cloud’s automatic schema change detection, you can manually refresh the source schema to stay up to date with changes in your schema [source](https://docs.airbyte.com/cloud/managing-airbyte-cloud/manage-schema-changes). If the error persists, it would be best to reach out to the Airbyte support team for further assistance. You can do this through their forum [source](https://discuss.airbyte.io/t/3028) or Slack channel.

@kapa.ai also getting this error
Copy code
Internal Server Error: Cannot invoke "io.airbyte.api.model.generated.AirbyteCatalog.getStreams()" because "discovered" is null

A message from kapa.ai
The error message you're seeing suggests that the 
discovered
object, which should contain the Airbyte Catalog, is null. This could be due to a problem with the 
discover
method in your source connector. The 
discover
method is responsible for returning a JSON object called a 
catalog
that describes what data is available and metadata on what options are available for how to replicate it [source](https://docs.airbyte.com/connector-development/tutorials/building-a-python-source). If you're developing a custom connector, make sure your 
discover
method is implemented correctly and returns a valid catalog. If you're using a pre-built connector, there might be an issue with the connector itself or the configuration you're using. If the issue persists, it would be best to reach out to the Airbyte support team for further assistance. You can do this through their forum [source](https://discuss.airbyte.io/t/3028) or Slack channel.

Copy code
Internal Server Error: Cannot invoke "io.airbyte.api.model.generated.AirbyteCatalog.getStreams()" because "discovered" is null
this looks a problem with the source
c
Are there other steps needed to convert an existing source for the upgrade?
m
Sources and destination will upgrade only patch versions, it should cause you trouble though
c
It should cause issue?
The connections all are full refresh that I am testing, and I have not been able to have a sync complete in the last few days
