SOLVED IPBX 2021 migrated from IPBX 2020 - Incredible Fax error

[undrhil]

I followed the instructions in the Wiki for migrating from a IPBX 2020 system using IncredibleFax. After the migration, my trunks and extensions are all defined and I am able to access the AvantFax web portal for sending faxes. However, after I put in my info and click Send, I get the following error message on the Status screen

Problem sending the fax.
sendfax: /var/www/html/avantfax/tmp/1fee4d2c.ps: Empty file

If I uncheck the Use Cover Page option and select a file (a one page PDF), I get the following error message on the Status screen

Problem sending the fax.
sendfax: 460 Failed to submit job 194: Unable to open scheduler FIFO: No such device or address

So, I had tested this several times since I did the install and it was not working. I kept getting the same errors.

However, yesterday I went through the article for adding the GUI to my IPBX 2021 system and after going through that article and getting the GUI working, the faxes are working now,

I don't know why. Unless there was something missing and apt-get update installed it, there doesn't seem to be any correlation between these two systems.

But it is working now and I have a GUI! So, it's a win-win!

Its always a win-win when the OP manages to answer his own question - well done.
