PostgresDB 22002: Null Value No Indicator Parameter

What is PostgresDB 22002: Null Value No Indicator Parameter

Immediately run the query that produced the error with NULL checks on all parameters that could potentially be NULL. For example, if your query is something like:

SELECT * FROM your_table WHERE your_column = $1;

And $1 could be NULL, modify your query to explicitly handle NULL values, like:

SELECT * FROM your_table WHERE your_column IS NOT DISTINCT FROM $1;

Or, if you're inserting/updating data, ensure that any column that does not accept NULL values is provided with a non-null value or has a default value set. For an insert, it might look like:

INSERT INTO your_table(column1, column2) VALUES ($1, COALESCE($2, 'default_value'));

Also, examine your application's logs to see the exact query that caused the error. This helps in identifying the parameter that was passed as NULL unexpectedly.
