Error when uploading; the file name is invalid, or the file is too big

Hi Guru,

I am trying to upload an .txtl file via WDA using File Upload UI element in sap crm. But application is throwing me following exception when i am trying to click submit button.

Error when uploading; the file name is invalid, or the file is too big

System is throwing above error even for a file with size 3 KB.

I also tried with the standard WDA : WDR_TEST_UI_ELEMENTS. I am getting the same error there.

Does some one knows, the root cause of this error.

Thanks,

Regards
