Dynamics 365 WebApi - BATCH 请求 - 错误 - 消息 header ' ' 无效

Dynamics 365 WebApi - BATCH request - Error - The message header ' ' is invalid

有人在尝试对 Dynamics 365 WebApi 执行 BATCH 请求时遇到以下错误消息吗?我正在使用 Postman。

{
    "Message": "The message header '  ' is invalid. The header value must be of the format '<header name>: <header value>'.",

除了 Batch request unique identifier & headers 之间的额外白线外,没有任何问题,错误可能就是因为这个。删除多余的白线,如下所示:

我遇到了同样的问题,只是说消息 header '\t' 无效。在我的空白行之一上,我有一个我看不到的制表符。找到并删除后,我的请求就顺利通过了。
