Image variation API endpoint error

znilsen · August 29, 2023, 9:06pm

Hello, I am having an issue with the image variations endpoint. I will have my body posted below of information, but I am guessing it has something to do with the file not being sent right somehow. I keep getting the error message, { “error”: { “code”: null, “message”: “‘image’ is a required property”, “param”: null, “type”: “invalid_request_error” } }

Any information on this would be appreciated, but I cannot exactly figure out what is wrong here.

Here is some coldfusion code provided below (dont expect anyone to know coldfusion, but it may help somewhat with the issue at hand)

<cfset LOCAL.httpRequest = CreateObject("java", "org.apache.http.client.methods.HttpPost").init(LOCAL.url) />

<cfset LOCAL.httpRequest.setHeader("Authorization", "#LOCAL.authorization#") />
<cfset LOCAL.httpRequest.setHeader("OpenAI-Organization", "#LOCAL.organization#") />
  
<cfset LOCAL.httpRequest.setHeader("Content-Type", "multipart/form-data") />
<cfset LOCAL.httpRequest.setHeader("Content-Type", "application/json") />
        
<cfset LOCAL.entityBuilder = CreateObject("java", "org.apache.http.entity.mime.MultipartEntityBuilder").create() />

<!-- Add the image file part -->
<cfset LOCAL.filePart = CreateObject("java", "org.apache.http.entity.mime.content.FileBody").init(
    CreateObject("java", "java.io.File").init(arguments.imagePath),
    "image/png"
) />

<cfset LOCAL.entityBuilder.addPart("image", LOCAL.filePart) />

<!-- Loop through the requestBody structure and add fields as text body parts -->
<cfloop collection="#arguments.requestBody#" item="LOCAL.fieldName">
    <cfset LOCAL.fieldValue = arguments.requestBody[LOCAL.fieldName]>
    <cfset LOCAL.entityBuilder.addTextBody(LOCAL.fieldName, LOCAL.fieldValue) />
</cfloop>


<!-- Create the HttpEntity and set it to the request -->
<cfset LOCAL.httpEntity = LOCAL.entityBuilder.build() />
<cfset LOCAL.httpRequest.setEntity(LOCAL.httpEntity) />

<cfset LOCAL.responseObj = LOCAL.httpClient.execute(LOCAL.httpRequest) />
<cfset LOCAL.respEntity = LOCAL.responseObj.getEntity() />
<cfset LOCAL.response = isDefined("LOCAL.respEntity") ? LOCAL.entityUtil.toString(LOCAL.respEntity, CreateObject("java", "java.nio.charset.StandardCharsets").UTF_8) : "" />

I think there is an issue with the Content-Transfer-Encoding: Binary, but the problem is I am using javas apache http library for this and I cannot disable this as the library sets this automatically- so I am thinking this is a bug on their end as I have a similar call with the exact same data and everything matches and it is working. Problem is I need to do the call this way for our code.
