  1. Error Code Guide

Function

Validation Errors#

FUNCTION_MISSING_CODE#

No Python code to execute is specified in the Function node.
Enter Python code in the code property in the Function node settings.
Check whether the Python code you entered is not empty.

FUNCTION_MISSING_REMOTE_URL#

The remote_url property required to run the Function node is not configured.
Enter the remote execution server URL in the remote_url property in the Function node settings.
Check whether the remote execution server is configured correctly.

Network Errors#

FUNCTION_DNS_FAILURE#

DNS lookup failed while running the Function node. The server address configured in remote_url may be incorrect or unreachable.
Check whether the server address configured in remote_url is correct.
Check whether the server is connected to the network and responding.
Update remote_url in the workflow builder or use another available server address.

FUNCTION_CONNECTION_REFUSED#

The Function node was refused by the server. The external execution server is not responding.
Check whether the external execution server is running.
Check whether the Function node settings are correct.
Check whether there is any problem with the network connection.

FUNCTION_CONNECTION_TIMEOUT#

The Function node failed to connect to the external server. It did not receive a response within the configured time.
Check the network connection status of the Function node.
Check whether the url is correct in the Function node settings.
Check whether the external server is operating properly.
Increase the timeout setting of the Function node.

FUNCTION_READ_TIMEOUT#

The execution time of the Function node has been exceeded. The function did not complete within the configured time.
Increase the timeout_ms value in the Function node settings.
Review the logic of the Function node to reduce execution time.
If the Function node calls an external API, check the API response time.

FUNCTION_WRITE_TIMEOUT#

It took too long for the Function node to send a request to the external server.
Increase the execution time of the Function node.
Check the response time of the external server.
Reduce the response time of the API used by the Function node.

FUNCTION_SSL_ERROR#

The Function node failed to establish a secure SSL/TLS connection. There may be a problem with the certificate of the external server.
Check whether the address entered in the url property of the Function node supports HTTPS.
Check whether the SSL certificate of the external server is valid.
Use another HTTPS address in the workflow, or consider using an HTTP address.

FUNCTION_REMOTE_TIMEOUT#

The Function node did not return a result within the configured time.
Increase the timeout_ms value of the Function node.
Optimize the code inside the Function node to reduce execution time.
If the Function node calls an external API, check the response time of that API.

FUNCTION_REMOTE_CONNECTION_ERROR#

The Function node failed to execute because it could not connect to the remote server.
Check whether remote_url is correct in the Function node settings.
Check whether the remote server is running.
Check whether there is any problem with the network connection.

Processing Errors#

FUNCTION_EXECUTION_ERROR#

An error occurred while executing code in the Function node. There may be a problem with the input variables or the code logic.
Review the code in the Function node and fix any syntax errors.
Check whether the types of the input variables match the types expected by the code.
If external libraries are used, check whether those libraries are imported properly.
Enable the Error Logging option in the Function node settings to review detailed error information.

FUNCTION_UNKNOWN_ERROR#

An unexpected error occurred while running the Function node.
Check whether the node settings are correct.
Check the function server logs to identify the cause of the error.
Review and fix the function code.

FUNCTION_INVALID_RESPONSE#

The Function node failed to execute. The response structure from the remote server is different from what was expected.
Check whether the function server is compatible with the STORM platform.
Check whether the response format of the function server is correct.
Review the function server connection information again in the Function node settings.
