Hi,
Below are my inline comments
So you're using file parameter, and runing from controller, is it? Are you using Linux or Windows LG?
[Rajiv] - Yes i'm using file parameter and running from Controller. i'm using Windows LG.
I think you can check following points,
1) Is there some other script lines saving values to the parameter {URL}?
[Rajiv] - Yes, The parameter {URL} is through out the script.
2) You can try the "simulate parameter" functionality in VuGen(as I posted in attachment), is it works as expect?
[Rajiv] - I tried simulate parameter in VuGen and it works as expected. (Please find the attachment).
3)If "simulate parameter" works as expect, but LG just randomly generate empty parameter, you can have a double check of the parameter .dat file deployed to LG, and please tell us the LR version number and share a sample parameter file(.prm and <param_name>.dat in script directory).
[Rajiv] - 1. How to cross check the parameter.dat file deployed to LG ? Could you please explain.
2. I'm using LR 12.50 with Patch 1. (Note : i'm getting this error before and after Patch update).
3. i'm unable to attach .dat and .prm file getting this error.
The file URL.dat does not have a valid extension for an attachment and has been removed. jpg,gif,png are the valid extensions.
The file XXX.prm does not have a valid extension for an attachment and has been removed. jpg,gif,png are the valid extensions.
i'm trying my level best to get resolved. Please help me in resolving this issue.
