validate-state-machine-definition

Description

Validates the syntax of a state machine definition.

You can validate that a state machine definition is correct without creating a state machine resource. Step Functions will implicitly perform the same syntax check when you invoke CreateStateMachine and UpdateStateMachine . State machine definitions are specified using a JSON-based, structured language. For more information on Amazon States Language see Amazon States Language (ASL).

Suggested uses for ValidateStateMachineDefinition :

  • Integrate automated checks into your code review or Continuous Integration (CI) process to validate state machine definitions before starting deployments.
  • Run the validation from a Git pre-commit hook to check your state machine definitions before committing them to your source repository.

Note

Errors found in the state machine definition will be returned in the response as a list of diagnostic elements , rather than raise an exception.

Options

--definition (string)

The Amazon States Language definition of the state machine. For more information, see Amazon States Language (ASL).

--type (string)

The target type of state machine for this definition. The default is STANDARD .

Possible values:

  • STANDARD
  • EXPRESS

--severity (string)

Minimum level of diagnostics to return. ERROR returns only ERROR diagnostics, whereas WARNING returns both WARNING and ERROR diagnostics. The default is ERROR .

Possible values:

  • ERROR
  • WARNING

--max-results (integer)

The maximum number of diagnostics that are returned per call. The default and maximum value is 100. Setting the value to 0 will also use the default of 100.

If the number of diagnostics returned in the response exceeds maxResults , the value of the truncated field in the response will be set to true .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

result -> (string)

The result value will be OK when no syntax errors are found, or FAIL if the workflow definition does not pass verification.

diagnostics -> (list)

If the result is OK , this field will be empty. When there are errors, this field will contain an array of Diagnostic objects to help you troubleshoot.

(structure)

Describes an error found during validation. Validation errors found in the definition return in the response as diagnostic elements , rather than raise an exception.

severity -> (string)

A value of ERROR means that you cannot create or update a state machine with this definition.

code -> (string)

Identifying code for the diagnostic.

message -> (string)

Message describing the diagnostic condition.

location -> (string)

Location of the issue in the state machine, if available.

For errors specific to a field, the location could be in the format: /States/<StateName>/<FieldName> , for example: /States/FailState/ErrorPath .

truncated -> (boolean)

The result value will be true if the number of diagnostics found in the workflow definition exceeds maxResults . When all diagnostics results are returned, the value will be false .
