You'll encounter unexpected `<EOF>` syntax errors in Snowflake when the SQL compiler encounters an obstacle while parsing your code, such as an incomplete statement or missing parameters, causing it to terminate and display this error message, which can be confusing due to its ambiguous text; these errors can occur from most SQL commands run in Snowflake and can be fixed by adding missing required syntax elements, using the correct directory path with the PUT command, and ensuring all elements are present in the command line, as error messages are helpful tools for debugging processes.
