autodesk-forge - GEN_SIZE_INVALID，详细信息：传递的对象大小太大，无法处理
问题描述
当使用 autodesk-forge 的 web 服务通过资源“data/v1/projects/{PROJECT_ID}/versions?copyFrom={ESCAPED_VERSION_ID}”复制文件版本时，以下 HttpResponse-Content 的实际含义是什么？
{"jsonapi":{"version":"1.0"},
"errors":[{
"id":"3a6cb28b-6656-451c-acfb-1c68ddb24a45",
"status":"400",
"code":"ERR_BAD_INPUT",
"title":"The request has invalid header or body",
"detail":"GEN_SIZE_INVALID, details: The object size passed is too big for processing."
}]}
可以引用的版本数量或类似内容是否有限制？
这是带有虚拟值的有效负载：

解决方案
From all the data we've been able to gather so far: There is in fact a limit on how many files can be referenced directly, which seems to be 50.
The reason it occurred in so many places for us when we didn't have any files referencing nearly that amount of other plans, was how the "CopyFrom"-functionality works.
Example on how to reproduce the problem:
Given "plan A" and "plan B" ("B" referencing "A"), upload both files and create their initial items/versions. Now do the following:
1.) re-upload "A" and create a new version.
2.) use "CopyFrom" on the latest version of "B" and define the reference to the latest version of "A".
Since "CopyFrom" adds references instead of replacing them, version #2 of "B" now holds two references. One towards the initial version #1 of "A" and one to the latest version of "A". Repeat these steps enough times and you'll eventually run into this issue.
Solution:
Even though nothing except one reference has changed on "B", one needs to reupload the file defining all required references so version #N of "B" only references version #N of "A". (Be wary that this behaviour of course may change in the future!)
