I'm getting the following response, when trying to upload data to BigQuery using the Google API Client libraries for Go.
{
"error": {
"errors": [
{
"domain": "global",
"reason": "badRequest",
"message": "Invalid Upload Request"
}
],
"code": 400,
"message": "Invalid Upload Request"
}
}
My job descriptor looks like this:
j := &bigquery.Job{
Configuration: &bigquery.JobConfiguration{
Load: &bigquery.JobConfigurationLoad{
DestinationTable: &bigquery.TableReference{
projectId,
"xyz",
name + "_" + yyyymmdd,
},
SkipLeadingRows: 1,
FieldDelimiter: "|",
MaxBadRecords: 3,
Schema: &bigquery.TableSchema{
[]*bigquery.TableFieldSchema{
{Name: "f1", Type: "STRING"},
{Name: "f2", Type: "STRING"},
{Name: "f3", Type: "STRING"},
{Name: "f4", Type: "STRING"},
{Name: "f5", Type: "STRING"},
{Name: "f6", Type: "STRING"},
{Name: "f7", Type: "STRING"},
{Name: "f8", Type: "STRING"},
{Name: "f9", Type: "STRING"},
{Name: "f10", Type: "STRING"},
{Name: "f11", Type: "STRING"},
{Name: "f12", Type: "STRING"},
{Name: "f13", Type: "STRING"},
{Name: "f14", Type: "STRING"},
{Name: "f15", Type: "STRING"},
{Name: "f16", Type: "STRING"},
{Name: "f17", Type: "STRING"},
},
},
},
},
}
FWIW, other calls using this library work fine, so I have ruled out oauth problems, etc.
EDIT: I captured the request before it went out. Please note that this is before the http.Client is able to add the oauth headers. The actual request is large, so I have shortened it and removed the identifiers.

It turns out that this was caused by a bug in the library that was not sending the required "uploadType" query parameter. See these diffs for a patch that fixes the bug.
However this exposed another bug in the library that I am currently working with the author to fix. I will update this answer when that fix is in.
EDIT: As of this patch, the bug referenced above is fixed.
