meta_request | Extract from RailsPanel

I did finally figure out what this was.
The older versions of rails in this case v4.2.1 used the javascript_include_tag for the line that deals with application:

= javascript_include_tag "application"

In the newer versions of rails in my case v6.1.3.1 you have to use javascript_pack_tag

= javascript_pack_tag

This solved the issue and the views all started working. I did mention above I was working on a PC running Rails v6.1.3; however I noticed I didn't make it clear that I was also having to upgrade this program from Ruby v2.2.2 and Rails v4.2.1 to Ruby v 2.7.2 and Rails v6.1.3, that might have helped to have made that more clear. Apologies if that confused anyone. I am still VERY new to Rails and using StackOverflow.com. I am happy to report I have only 1 single issue left on this program and the rest of the program is all working properly. I will be posting another question in fact because the last issue deals with a complicated scope query and it uses different syntax again due to the newer version of rails and I haven't been able to figure it out. In any even if you are running an older version of Rails and you are trying to get the program to work on a newer version (my case as I couldn't get rails v4.2 to run or work on ANYTHING, PC, Linux nothing) then you have to change the include_tag to a pack_tag. I do not pretend to say I fully understand why. I know it has to do with webpacker but beyond that I am still learning Rails. Perhaps someone with more knowledge than myself can shed some insite as to why the syntax changed. Oh and in addition the line ended up needing to read as follows:

= javascript_pack_tag "application", "data-turbolinks-track": "reload"

I didn't have the turbolinks reference either.

I hope this helps someone else in a similar situation that I was in, it was not easy to find. I only discovered it when I went through some tutorials on making other generic apps and saw the difference on that line.

So... It seems this line in ActiveSupport v6.0.3.6 is calling this method in redis with 3 arguments instead of 2; exactly like the error says!

And just as I suspected, that's already been fixed in the master branch. Here was the commit that introduced the fix.

So in other words, I reckon you've found a bug in rails 6.0 working with ruby 3.0.

Additionally, it seems that this bug has already been backported into the 6.0-stable branch and, according to the comments, "will be included in Rails 6.0.4".

tl;dr: Either downgrade ruby back to 2.7, or upgrade rails to 6.1, or add to your Gemfile:

Looks like you're running into compatibility issues trying to use the latest version of the activerecord-import gem at the time of writing (released in October 2020) with activerecord 3.2.22.5 (released in September 2016). You do mention it's a rails 3.2.15 app but you're not using activerecord 3.2.15 which is confusing.

Try using activerecord-import 0.4.1 (released in July 2013) and activerecord 3.2.15 which should be compatible with rails 3.2.15.

This is probably and error with the stylesheet_link_tag and stylesheet_pack_tag, check out your layout files probably you are including sass files and you are using stylesheet_link_tag, this is breaking your code given that as I understand you can just link plane css files. so if you are including sass files use the stylesheet_pack_tag
