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.
