I have done something similar like it is defined in this tutorial, so I have published one cds entity and try to build Java module with OData v4.
I can get the objects using GET resource and can even POST the object. However, this works only in case when I don't try to POST something to largeBinary field. I cannot reach the breakpoint inside my createObject method because I get the following error (400 Bad Request):
{
"error": {
"code": "OLINGO LIBRARY EXCEPTION",
"message": "Invalid value for property 'content'."
}
}
This is the case when I try to send String or encoded base64 string. In this case I don't come to my method (breakpoint).
However, when I send null it is reached even though I get another error (500 Internal Server Error):
{
"error": {
"code": "OLINGO LIBRARY EXCEPTION",
"message": "while trying to invoke the method org.apache.olingo.commons.api.data.Property.getValue() of a null object returned from org.apache.olingo.commons.api.data.Entity.getProperty(java.lang.String)"
}
}
After this post request brought me the object in database and I try to reach the content using myObjects("idOfObject")/$value and get the following error:
{
"error": {
"code": "OLINGO LIBRARY EXCEPTION",
"message": "The resource 'EmailAttachment' is not a media resource. $value can only be applied on media resources."
}
}
So, my question is:
How to pass binary data into Java customer exit?
P.s. The method where I have a breakpoint is annotated like this:
@ExtendDataProvider(entitySet = { "MyObject" }, requestTypes = RequestType.CREATE)
