What causes 100183 (P0001)?

A JavaScript exception (TypeError, ReferenceError) inside the UDF code. A null or undefined value passed to the UDF that the JavaScript code does not handle. The UDF attempts to access a property of null (e.g., null.value). An incorrect data type is passed to the UDF (e.g., a string where a number is expected). Division by zero or other arithmetic error inside the JavaScript logic

How do I fix 100183 (P0001)?

Read the full error message — Snowflake usually includes the JavaScript exception type and a stack trace. Add null checks at the beginning of the UDF: if (input === null || input === undefined) return null;. Test the UDF with edge case inputs (null, empty string, 0, very large numbers) before production use. Add try-catch inside the JavaScript UDF to return a meaningful error value instead of throwing. Review the UDF code for type assumptions that may not hold for all input values

Power BI Refresh Error:
100183 (P0001)

What does this error mean?

An exception was thrown inside a Snowflake JavaScript user-defined function (UDF) or stored procedure during execution. The error originates from within the JavaScript code, not from Snowflake SQL.

Common causes

1A JavaScript exception (TypeError, ReferenceError) inside the UDF code
2A null or undefined value passed to the UDF that the JavaScript code does not handle
3The UDF attempts to access a property of null (e.g., null.value)
4An incorrect data type is passed to the UDF (e.g., a string where a number is expected)
5Division by zero or other arithmetic error inside the JavaScript logic

Frequently asked questions

Can I get the full JavaScript stack trace from Snowflake?

Yes — the error message from Snowflake includes the JavaScript exception class and message. For deeper debugging, add console.log statements (viewable in query history) or use try-catch to return error details.

Are Python UDF errors the same error code?

Python UDFs in Snowflake have their own error codes. 100183 specifically applies to JavaScript UDFs and stored procedures.
