"CG 1-19 ADD 1 "CRAWL_NORMAL" 1 ''\r\n" - "Missing parameter. Check syntax" error

General
1

Hi. I’m using CasparCG Server 2.3.2 4de6d18f Dev x64 in conjuction with TVPlay. I was previously using the TVP fork of CasparCG, but due to problems with “Flash call failed” I had to switch to the main branch. I’m trying to run the command “CG 1-19 ADD 1 “CRAWL_NORMAL” 1 ‘’\r\n” which should load a .ft template in the templates folder, and the “Missing parameter. Check syntax” error occurs. I don’t know what causes the problem. Does anybody have a solution?
Here are the logs:

You don’t send any data to the template, but that should not trigger an error…

3

The problem is that you send empty string at the end. I just tested, that with the “” it returns this error, while without it it is working fine.

Thank you! Unfortunately it’s not directly me issuing those commands, but they come from TVPlay. The CgElementsControllers.xml which the program uses has the command “CG CG3 ADD 1 CRAWL_NORMAL 1”. Why does it add an additional empty string and how I can prevent that? I can attach the xml and dll file for the plugin if it’s neccessary.
