Hey there, thanks for reaching out! :) If you're encountering an unexpected error when trying to add a column in Clay, it could be due to hitting the limit of interconnected tables that Clay can handle, which is around 5-6 tables. If your "write to table" action is pointing to multiple tables, consider reducing the number of interconnected tables to resolve the issue. Additionally, try creating the "write to table" action again, as this has been known to work in some cases. If the error persists, it may be necessary to streamline the process to avoid such errors, as there is currently no fix for this known issue.
In general, unexpected errors can occur for various reasons, and without specific context, it's challenging to provide a precise solution. If you provide more details or the link to the table, I could further trouble shoot :)
