R Bigquery Error : attempt to apply non-function API Data Failed to Parse - r

Question

I am trying to do a simple Query with R and BigQueryR
https://github.com/cloudyr/bigQueryR:
I am not sure what is wrong but I keep getting an error (this might just be my lack of knowledge with R).
It is returning a list of projects and data sets correctly so I know it is connected.
I followed the guides on querying:
https://rdrr.io/cran/bigQueryR/man/bqr_query.html
bqr_query(projectId, datasetId, query, maxResults = 1000)
This is the command I put in:
result <- bqr_query("bigqyerytestproject2", "TestDataSet1", "SELECT * FROM TestTable3", maxResults = 1000)
and I get the error:
Error : attempt to apply non-function
Warning message:
In q(the_body = body, path_arguments = list(projects = projectId)) :
API Data failed to parse. Returning parsed from JSON content.
Use this to test against your data_parse_function.
But then I checked BigQuery and the query is going through successfully:
I am just connecting a small amount before I move a large data set but the results are:
[
{
"Name": "Season",
"Date": "2010-06-30",
"ID": "1"
},
{
"Name": "Test",
"Date": "2010-06-30",
"ID": "2"
}
]
Thanks in advance for your help

Answer 1

Depending on your app's needs, you might consider using bigrquery instead of bigQueryR. The difference is explained here.
Beyond that, I'd suggest filing an issue with the developer of the bigQueryR library.

Answer 2

I'll describe how I got past that same error in case it's helpful, though I think it might be a slightly different problem as mine was caused by a permissions error with Google Sheets.
To create the error, I can:
Create a Google Sheets spreadsheet
Use the spreadsheet as a source of a BigQuery table
Query the BigQuery table using bqr_query()
At this point an error will pop up due to insufficient permissions
After seeing the error I grant permission to edit the Google Sheet to my app
The error "Error : attempt to apply non-function" appears and I can't get rid of it.
If I don't query the table until after granting permission to my app, the error doesn't appear in the first place. So I just had to recreate the Google Sheet and BigQuery table.
Hope this helps!
