`vetiver.deploy_rsconnect` fails on rsconnect-python < 1.12.1

[SamEdwardes]

TL/DR

I think that vetiver needs to pin a requirement of rsconnect-python >= 1.12.1.

Reprex rsconnect-python==1.7.1

vetiver==0.1.8
rsconnect-python==1.7.1

Reprex rsconnect-python>=1.8.0 and rsconnect-python<=1.12.0

I tested under the following scenarios, they all go the same error:

• rsconnect-python==1.8.0
• rsconnect-python==1.8.1
• rsconnect-python==1.9.0
• rsconnect-python==1.10.0
• rsconnect-python==1.11.0

Ah, thank you for this! I do notice that your connect_server argument is the url, not a Connect Server object (see https://rstudio.github.io/vetiver-python/stable/reference/vetiver.deploy_rsconnect.html#vetiver-deploy-rsconnect). That should solve your error for some versions.

I still think this is a good idea to pin the version due to the other errors you are hitting, but starting at rsconnect-python>=1.11 rather than 1.12.1.

[SamEdwardes]

Thank you for taking a look @isabelizimm.

I was putting the wrong value into the connect_server argument. I found this example to be the most helpful: https://docs.posit.co/connect/user/vetiver/#example.

So I think I was incorrect to say that these versions do not work:

• rsconnect-python==1.8.0
• rsconnect-python==1.8.1
• rsconnect-python==1.9.0
• rsconnect-python==1.10.0
• rsconnect-python==1.11.0
• rsconnect-python==1.12.0

After fixing my code:

import os
import sys

import pins
import vetiver

from vetiver.data import mtcars
from sklearn.linear_model import LinearRegression
from rsconnect.api import RSConnectServer

# Fit a model ------------------------------------------------------------------

lm = LinearRegression().fit(mtcars, mtcars["mpg"])
model_name = "sam.edwardes/mtcars-linear-model3"

v = vetiver.VetiverModel(
    lm,
    model_name=model_name,
    save_ptype=True,
    ptype_data=mtcars
)

# Pin model --------------------------------------------------------------------

board = pins.board_rsconnect(
    server_url=os.getenv("CONNECT_SERVER"),
    api_key=os.getenv("CONNECT_API_KEY"),
    allow_pickle_read=True
)

vetiver.vetiver_pin_write(board, v)

# Deploy model -----------------------------------------------------------------

connect_server = RSConnectServer(
    url=os.getenv("CONNECT_SERVER"), 
    api_key=os.getenv("CONNECT_API_KEY")
)

vetiver.deploy_rsconnect(
    connect_server=connect_server,
    board=board,
    pin_name=model_name,
    python=sys.executable,
)

After making the code changes, I was able to deploy successfully using:

vetiver==0.1.8
rsconnect-python==1.8.0

So maybe vetiver should just be pinned to require rsconnect-python>=1.8.0?
