OSError: [E941] Can't find model 'en'. It looks like you're trying to load a model from a shortcut, which is obsolete as of spaCy v3.0. To load the model, use its full name instead:

nlp = spacy.load("en_core_web_sm")

For more details on the available models, see the models directory: https://spacy.io/models. If you want to create a blank model, use spacy.blank: nlp = spacy.blank("en")

The upgrade of spacy to >=3.0 was in d8b330db94f502e293797e32e52fef07903beea8

This feature is deprecated in the spacy 3.0, https://github.com/AICoE/sefkhet-abwy/blob/642862a3353bc73851c44c4ee18ecca8c2ad22a3/.s2i/bin/assemble#L7

that gives this issue:

DeprecationWarning: The command link is deprecated.
⚠ As of spaCy v3.0, model symlinks are not supported anymore. You can
load trained pipeline packages using their full names or from a directory
path.

[harshad16]

As this deprecated in spacy >3.x , we would have to update the language model version and update the chatterbot package to use the correct spacy feature. which seems to be extra work for the simple issue.

Instead of fixing the bot, we would downgrade the version of spacy which is causing the issue. we know the chat bot worked with the spacy ==2.3.5 , we would pin down the app to this version.
