Hello ! I was just playing with one model and it throws an error:

CloudEnv is deprecated, use Env(params={...}) instead

This is how I initially used CloudEnv:

``env=gp.Env.CloudEnv(logfilename="", accessID=GUROBI_ACCESS_ID, secretKey=GUROBI_SECRET_KEY)``

Now, I have tried the following, but to no avail:

` `env=gp.Env(params={"logfilename":"", "accessID":fr"{GUROBI_ACCESS_ID}", "secretKey":fr"{GUROBI_SECRET_KEY}"})``

I have tried to look up the deprecation warning in the docs but didnt find anything. What is the new correct syntax ? Thanks !

Hi Paul,

The parameter names to use are slightly different than the parameters to the original `CloudEnv` function. The syntax looks like this:
```
params = {
'CloudAccessID': '...',
'CloudSecretKey': '...',
'CloudPool': '...'
}
e = gp.Env(params=params)
```
Best regards,
Ronald

Sorry about that... the parameter names to be used as dictionary keys with this syntax are basically the official parameter names listed here. But I understand it can be confusing in the context of this deprecation message!

Additionally, are there any other changes to the API ? That's because a previously working model now spits 'the JSON object must be str, bytes or bytearray, not tuple'. Thank you !

Not sure... could you post a code snippet that illustrates the error?

It comes from a seemingly unrelated variable declaration. It's a bit weird because it worked a few days ago:

list_materials=json.loads(list_materials)['data'].

It probably is a mistake of mine so I will look further into each data structure ! Thanks !
