Hi all,
A client of ours has recently starting using the self-hosted API server. They're trying to use the following request to create new documents in Laserfiche via the API.
When doing this through the Swagger interface the request is successful and creates the document as expected. Running the same request from the application they wish to integrate with (developed in C#) the request fails.
Each time it fails there is an error logged in the API trace log (%ProgramData%\Laserfiche\API Server\LFRepositoryAPI\Logs\trace.log) which states "Property file not found in the request body". I'll copy the full error below. There is also a warning about MaxRequestBodySize, but I think this can be ignored as we also receive this for successful requests (maxAllowedContentLength and uploadReadAheadSize both set to 100 MB in IIS).
As it works through Swagger I'm guessing this is either an issue with how the document is being passed into the request or something tampering with the request before it gets to the API (the other application is in a DMZ so there are firewalls/anti-virus between the applications).
Has anyone seen this issue before? Or does anyone know precisely what the above error means?
Many thanks!
Dan
