How to pass args and template_fields to dataproc from airflow 1 - google-cloud-platform

Question

I am trying to execute python code on a dataproc cluster via airflow orchestration.
I am using airflow 1.10.12, and DataprocWorkflowTemplateInstantiateInlineOperator to instanciate a dataproc cluster & pass some parameters (and templated params aswell). The main objective is to run some prediction code.
Note that I upgraded this code so use airflow.providers.google.cloud.operators.dataproc and not airflow.contrib.operators.dataproc_operator to import DataprocInstantiateInlineWorkflowTemplateOperator, because the former introduced the parameters kwarg that, in theory, permits passing arguments to the cluster. Using the later in my other scripts, I have no errors, but I cannot introduce parameters to the cluster.
...
from airflow.providers.google.cloud.operators.dataproc import (
DataprocInstantiateInlineWorkflowTemplateOperator,
)
...
workflow_seg_members = make_workflow_template(
region=REGION,
dataproc_job_bucket=DATAPROC_JOB_BUCKET,
python_main_executable_path="segmentation_members/seg_members_prediction.py",
)
op_seg_members_prediction = DataprocInstantiateInlineWorkflowTemplateOperator(
task_id="seg_members_prediction",
project_id=PROJECT_ID,
region=REGION,
template=workflow_seg_members,
parameters={
"execution_date_str": "{{ds_nodash}}",
"project": "<REDACTED>",
"dataset": "<REDACTED>",
"features_table_prefix": "global_features",
"output_table_prefix": "seg_members_output",
"path_to_model": "segmentation_members/DecisionTreeClassifier.pkl",
"bucket_name": "<REDACTED>",
"model_designation": "Segmentation Members",
},
)
in seg_members_prediction.py, I use argparse to create the needed arguments.
The error I am getting is :
TypeError: Parameter to MergeFrom() must be instance of same class: expected google.cloud.dataproc.v1beta2.OrderedJob got str.
My questions are :
How do I fix this MergeFrom() exception?
Is this the right approach to pass parameters from airflow to my dataproc cluster?
Here is the complete stack :

EDIT :
I tried running the following code but still got the same error :
op_seg_members_prediction = DataprocInstantiateInlineWorkflowTemplateOperator(
task_id="seg_members_prediction",
project_id=PROJECT_ID,
region=REGION,
template=workflow_seg_members,
)
op_seg_members_prediction.execute(context="DEBUG")
After browsing the apache-airflow-providers-google doc I discovered it isn't compatible with airflow 1.
You can install this package on top of an existing Airflow 2
installation (see Requirements below for the minimum Airflow version
supported) via pip install apache-airflow-providers-google
The package supports the following python versions: 3.7,3.8,3.9,3.10
So I upgraded to airflow 2 in my local environment, and the MergeFrom() error stopped occurring.
This still begs the question : How do you pass parameters from airflow to dataproc for airflow 1
