+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+- API version: 0.5.1-SNAPSHOT.0
+
+- Generator version: 7.19.0-SNAPSHOT
+
+Api to reproduce bug
+
+
+*Automatically generated by the [OpenAPI Generator](https://openapi-generator.tech)*
+
+## Requirements
+
+Building the API client library requires:
+
+1. Java 1.8+
+2. Maven/Gradle
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+Refer to the [OSSRH Guide](http://central.sonatype.org/pages/ossrh-guide.html) for more information.
+
+### Maven users
+
+Add this dependency to your project's POM:
+
+```xml
+<dependency>
+  <groupId>org.openapitools</groupId>
+  <artifactId>additonal-properties-in-multipart-request-issue</artifactId>
+  <version>0.5.1-SNAPSHOT.0</version>
+  <scope>compile</scope>
+</dependency>
+```
+
+### Gradle users
+
+Add this dependency to your project's build file:
+
+```groovy
+  repositories {
+    mavenCentral()     // Needed if the 'additonal-properties-in-multipart-request-issue' jar has been published to maven central.
+    mavenLocal()       // Needed if the 'additonal-properties-in-multipart-request-issue' jar has been published to the local maven repo.
+  }
+
+  dependencies {
+     implementation "org.openapitools:additonal-properties-in-multipart-request-issue:0.5.1-SNAPSHOT.0"
+  }
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+```shell
+mvn clean package
+```
+
+Then manually install the following JARs:
+
+- `target/additonal-properties-in-multipart-request-issue-0.5.1-SNAPSHOT.0.jar`
+- `target/lib/*.jar`
+
+## Getting Started
+
+Please follow the [installation](#installation) instruction and execute the following Java code:
+
+```java
+
+import org.openapitools.client.*;
+import org.openapitools.client.auth.*;
+import org.openapitools.client.model.*;
+import org.openapitools.client.api.FileApi;
+
+public class FileApiExample {
+
+    public static void main(String[] args) {
+        ApiClient defaultClient = Configuration.getDefaultApiClient();
+        defaultClient.setBasePath("http://localhost:8080");
+        
+        FileApi apiInstance = new FileApi(defaultClient);
+        File documentBytes = new File("/path/to/file"); // File | 
+        String documentType = "documentType_example"; // String | 
+        Map<String, String> properties = new HashMap(); // Map<String, String> | 
+        StructuredType structured = new StructuredType(); // StructuredType | 
+        try {
+            apiInstance.createFile(documentBytes, documentType, properties, structured);
+        } catch (ApiException e) {
+            System.err.println("Exception when calling FileApi#createFile");
+            System.err.println("Status code: " + e.getCode());
+            System.err.println("Reason: " + e.getResponseBody());
+            System.err.println("Response headers: " + e.getResponseHeaders());
+            e.printStackTrace();
+        }
+    }
+}
+
+```
+
+## Documentation for API Endpoints
+
+All URIs are relative to *http://localhost:8080*
+
+Class | Method | HTTP request | Description
+------------ | ------------- | ------------- | -------------
+*FileApi* | [**createFile**](docs/FileApi.md#createFile) | **POST** /api/v1/file | 
+
+
+## Documentation for Models
+
+ - [StructuredType](docs/StructuredType.md)
+
+
+<a id="documentation-for-authorization"></a>
+## Documentation for Authorization
+
+Endpoints do not require authorization.
+
+
+## Recommendation
+
+It's recommended to create an instance of `ApiClient` per thread in a multithreaded environment to avoid any potential issues.
