PostgreSQL throws INVALID_JSON_TEXT when a supplied value is not valid JSON, preventing casts, inserts, or updates into json or jsonb columns.
INVALID_JSON_TEXT is raised when PostgreSQL tries to parse malformed JSON (SQLSTATE 22032). Supply syntactically correct JSON or validate the text with jsonb_validator before inserting or casting to resolve the error.
INVALID_JSON_TEXT (SQLSTATE 22032)
PostgreSQL assigns SQLSTATE 22032 to the condition name INVALID_JSON_TEXT.
The server raises it whenever it fails to parse a string as JSON while executing casts, implicit conversions, or JSON functions.
The error interrupts the statement to prevent corrupt or ambiguous data from entering a json or jsonb column, view, or expression result.
The condition appears during INSERT, UPDATE, or SELECT when a text literal or column is cast to json/jsonb, or when operators like -> or functions such as jsonb_array_elements expect valid JSON input.
It can also surface inside PL/pgSQL code, triggers, and COPY operations that feed data into json or jsonb columns.
Unfixed, the error blocks data ingestion pipelines, API endpoints, and ETL jobs that rely on JSON storage.
Repeated failures can stall downstream analytics and cause application outages.
Resolving the issue ensures data integrity, keeps services online, and prevents manual cleanup of partial writes.
.
Set log_min_error_statement=error and enable log_error_verbosity=verbose. PostgreSQL will record the statement and position where parsing stopped.
No. PostgreSQL follows the JSON RFC strictly. Comments and trailing commas will trigger INVALID_JSON_TEXT.
You can write a PL/pgSQL wrapper that attempts to strip problematic characters, but it is safer to fix the producer of the data.
Galaxy’s inline linting highlights malformed JSON literals before execution and its AI copilot can auto-correct quoting and escaping, reducing runtime errors.
