Function Status Code

Last updated: 2021-04-02 10:02:27

If an error code is returned after the function is executed, you can find the cause and solution for the error code by referring to the following table.

Status Code and Status Message	Description	Solution
200 Success	The execution is successful.	-
400 InvalidParameterValue	The input parameters are incorrect.	The parameter does not conform to the specification. Please modify it as instructed in Introduction and try again.
401 InvalidCredentials	The verification fails.	The verification fails. Your account does not have the permission to manipulate this function. Please check the permission and try again. For more information, please see the authorization description in Permission Management Overview.
404 InvalidSubnetID	The subnet ID is invalid.	Check whether the network configuration of the function is correct and whether the subnet ID is valid.
406 RequestTooLarge	The request body size is too large.	The request event size exceeds the upper limit, which is 6 MB for sync request events or 128 KB for async ones.
429 ResourceLimit	The container request rate is too high.	The container request rate is too high. Please try again later.
430 User code exception caught	A user code execution error occurs.	Based on the error log on the console, check the error stack of the code and see whether the code can be executed properly.
432 ResourceLimitReached	The concurrence limit is reached.	Container resource usage exceeds the upper limit (the number of concurrent functions * 2). Please adjust the code or submit a ticket to increase the function concurrency limit.
433 TimeLimitReached	The function execution times out.	Check whether a large number of time-consuming operations exists in the service code. Set a longer timeout period on the "Function configuration" page. If the current timeout period has been set to the maximum value, you can submit a ticket to increase the timeout limit.
434 MemoryLimitReached	The memory limit is reached.	Check the code logic to see whether there is a memory leak. Set a larger memory size on the "Function configuration" page. If the current memory size has been set to the maximum value, you can submit a ticket to increase the memory limit.
435 FunctionNotFound	The function is not found.	Check whether the function is deleted or whether the function information that is used as the input parameter is correct.
436 InvalidParameterValue	The parameter is invalid.	The parameter does not conform to the specification. Please modify it as instructed in Introduction and try again.
437 HandlerNotFound	The function package is loaded incorrectly.	The function entry file is not found. Please check whether the entry file name in the code package matches the handler settings and whether the code package is normal. For more information on the handler, please see Execution method.
438 FunctionStatusError	The SCF service is suspended because the Tencent Cloud account is overdue.	The SCF service is suspended because the Tencent Cloud account is overdue. Please top up and try again.
439 User preocess exit when running	The user process exits accidentally.	Based on the error message, find out the cause and fix the function code.
440 BorrowContainerDegrade	The borrowed container circuit breaker is triggered.	The borrowed container circuit breaker is triggered. This may be because that the expansion speed or concurrency exceeds the limit. Please submit a ticket to increase the expansion speed or concurrency quota.
441 UnauthorizedOperation	CAM authentication fails.	Check whether the CAM authentication parameters for the function invoker are passed correctly. For more information, please see the authorization description in Permission Management Overview.
442 QualifierNotFound	The specified version is not found.	The function version does not exist. Please check the function version and try again.
443 UserCodeError	A user code execution error occurs.	Based on the error log on the console, check the error stack of the code and see whether the code can be executed properly.
450 InitContainerTimeout	The user code container times out.	The user code container times out (15s). Please check the code and try again. If the problem persists, please submit a ticket.
500 InternalError	An internal error occurs.	An internal error occurs. Please try again later. If the problem persists, please submit a ticket.

Concepts

Execution method

The execution method specifies the starting file and function while invoking the cloud function as shown below:

For Go programming, use the FileName format, such as main.
For Python, Node.js, or PHP programming, use the FileName.FunctionName format, such as index.main_handler.
- Please note that FileName does not include the file name extension, and FunctionName is the name of the entry function. Ensure that the file name extension matches the programming language. For example, for Python programming, the file name extension is .py, and for Node.js programming, the file name extension is .js. For more information, please see "Execution Method" in Basic Concepts.
For Java programming, use the package.class::method format, such as example.Hello::mainHandler.
For the Custom Runtime environment, a non-fixed format can be used based on the custom programming language implementation.
