It seems that as per MS-WOPI protocol specification, the JSON object returned as response of an operation should have it's key names in PascalCase format. For example CheckFileInfo.
Some development frameworks (such as .NET 5) automatically default to camelCase. This can easily go unnoticed.
Perhaps it is wise to include an "Important" information piece, that highlights this fact.
