Yes, probably. The only reason why you’d need a plugin is if you were trying to change the API (ie back end).
I’ve had a similar issue in the past.
Yes, you need to change app.yml to allow large files to be fed through the reverse proxy (nginx).
Thankfully this is a simple setting, upload_size:, here in context:
params:
## Which Git revision should this container use? (default: tests-passed)
version: tests-passed
## Maximum upload size (default: 10m)
upload_size: 20m
Once you’ve changed this you will need to rebuild for it to take effect:
./launcher rebuild app
Of course, this assumes you have appropriate access to the server …
