Unable to Upload Target Gem in COSMOS 5

[Donny3000]

Good Morning COSMOS Team,

I've been able to successfully install/build COSMOS 5 from master/main (616ad92) and start the application in the browser. So, I proceeded with the COSMOS 5 "Getting Started" tutorial. completing the "Getting Started" and "Interfacing with your Hardware" sections. Starting the "Building Your Plugin" section, I completed step one with the following output

However, when proceeding to upload the gem to COSMOS, I get the following 500 error

Does anyone know why I might be seeing this?

I would open the devtools of your browser and look at the network tab find the response that is a status code of 400 or 500 and view the error. Check out this writeup on debugging cosmos #1334 (comment)

We are working to clean up errors and make sure we provide some good error messages so this should get better over time. When working with loading plugins Cosmos still need to solve the problem of how to load external gems. I would also take a look at #1354

I need to double check that we have this in the getting started pages but, if your plugin requires an external dependency you will need to update the cosmos gemspec file and rebuild the container.

An example of adding external gems to the cosmos/cosmos.gemspec file.

  s.add_runtime_dependency 'tzinfo-data', '~> 1'
+  s.add_runtime_dependency 'google-protobuf', '~> 3.17'
+  s.add_runtime_dependency 'protobuf'

Thanks, @gerhardatball for the info! Looking at the development tools in chrome, I saw where my plugin.txt was malformed. Correcting that issue resolved my upload issue. Thanks again!
