API Builder Standalone - 21 June 2019

API Builder Standalone - Valencia

Summary

This release includes:

Upgrade

To update an existing API Builder Standalone application, execute the following command from within the application directory:

npm update

Fixes

  • #5620: Fix string-based model queries on dates, booleans and number fields
  • #5819: Fix invalid JSON Schema and Swagger documentation generated for models that have PK of type date

Release Notes

  • #5620: The Memory connector has been updated to use Version 2 of the "mingo" dependency for data storage and queries. This fixes multiple issues, including problems finding and updating objects and dates. Note that trying to use any unknown operators, such as $foo, when querying on the Memory connector will result in an error.

  • #5620: Previously, there were issues when using strings to query date, number, and boolean fields on findAndModify, query, count, and distinct model methods. Queries such as '\{ "DATE": { "$gt": "2020-10-10" } }' would fail to work causing database errors. Now, the values in queries are interpreted as the correct type when interacting with the underlying database.

  • #5819: Previously, the service would fail to start when loading a Model with a Date as a Primary Key. Now, the service will start.

  • #5819: Previously, when generating Swagger documentation for your service, certain parameters which are Date fields internally would be represented using type: 'string' and format: 'date' or 'date-time'. This format didn't allow for the variety of date formats that work when calling the API, so certain inputs would be rejected if validated against the Swagger documentation. Now, the format has been removed, allowing any date format to be provided.

Updated modules

Known Issues

  • #3825: Filtering the API Builder Console administrator access using IPv6 addresses may cause ENOTFOUND errors.

  • #3867: When attempting to create and save a flow for an imported Swagger endpoint that contains a path or paths defined by references, the save will fail.

  • #3979: Attempting to delete an endpoint in the UI that was created as a result of dereferencing a JSON $ref will yield a 404 error. API Builder will fail to locate the method since it only exists when the whole Swagger document is dereferenced. An example of a Swagger document using $ref:

    {
    	"swagger": "2.0",
    	"paths" {
    		"x-path": {
    			"get": {}
    		},
    		"/find": {
    			"$ref": "#/paths/x-path"
    		},
    		"/search": {
    			"$ref": "#/paths/x-path"
    		}
    
    	}
    }
    
  • #4528: Initializing a new project with api-builder init 1234 where 1234 is any number will throw an ERR_INVALID_ARG_TYPE error rather than an "invalid npm package name" error.

  • #4595: When using a distinct API backed by the Memory connector and passing a field which does not exist on the model, the first record is returned instead of an error.

  • #4735: Invoking Upsert will fail for all data connectors when creating a composite model from an existing model and renaming one of the fields.

  • #4749: A query on a distinct API created from the Mongo plugin (@axway/api-builder-plugin-dc-mongo) does not honor the value of the order parameter.

  • #4750: The Upsert or FindAndModify methods are not present in the APIs generated from Mongo or MySQL connector based models.

  • #4751: The FindAndModify method from APIs created using the Mongo plugin (@axway/api-builder-plugin-dc-mongo) responds with a 404 error rather than creating a new entry when the upsert parameter is true.

  • #4752: The format of a distinct query response depends on the type of connector.

  • #4759: Calling Update or FindAndModify on a model that uses the composite connector and contains the required fields may fail and cause the server to terminate.

  • #4795: The MongoDB plugin @axway/api-builder-plugin-dc-mongo does not support primary keys that are not object identifiers correctly. The MongoDB specification allows for primary keys of other types. As a result, trying to use the plugin will result in errors:

     { "message": "Invalid Value for Find By ID: "YOUR_STRING_PK_NAME", "success": false, "request-id": "c118f187-2090-4a68-b939-37367ac55b80" }
    
  • #4813: If the endpoint Swagger file in the /endpoints folder contains special characters in its name, for example [test].json, the endpoint is not rendered correctly in the UI.

  • #4856: Passing in an invalid column name as a parameter to APIs generated from data connectors may result in an exception being thrown rather than the callback being executed with an error. A similar error may occur when using model flow-nodes, resulting in an error which cannot be handled by the flow.

  • #4859: When endpoints are generated from a model, the endpoint descriptions do not use the correct plurals defined by the model.

  • #4865: The Swagger flow-node plugin strips characters from valid object definition names which can result in schema ID collisions.

  • #4865: The Swagger flow-node plugin does not handle valid object definition names with ~ or / in their name which can result in an invalid schema references in Swagger flow-nodes.

  • #4951: When endpoint or flow files with URL encoded characters in the filename are present in a project, unexpected errors may occur. For example, the wrong flow or endpoint could be modified. Using files with encoded characters in their names is not recommended.

  • #4961: Having the % symbol in various file names can cause problems in the API Builder Console and with direct linking. It is therefore advisable to avoid using % in API, Endpoint, Flow, Model, and Configuration file names. This is a result of an issue in react-router/history. For additional information, refer to https://github.com/ReactTraining/history/issues/505.

  • #4966: API Builder will generate invalid Swagger for programmatic APIs in ./apis that bind to a path other than the apiPrefix defined in the configuration. These APIs must be bound to the same root path as defined by the apiPrefix.

  • #5538: A model with a single-quote "'foo" is a valid model name, but not a valid endpoint name, so the single-quote will be stripped when generating endpoints. If another model "foo" exists and has generated endpoints, then generating endpoints for "'foo" with single-quote, will overwrite existing endpoints for "foo". The following characters are stripped from model names: "?", ":", "'", and ".".
