getting below error while ingesting data using ingestFromURI API :

curl: (3) URL using bad/illegal format or missing URL

my code :

curl -X POST "<https://localhost:9000/ingestFromURI?tableNameWithType=transcript_OFFLINE>
&batchConfigMapStr={
  "inputFormat":"csv",
  "recordReader.prop.delimiter":",",
  "input.fs.className":"org.apache.pinot.plugin.filesystem.S3PinotFS",
  "input.fs.prop.region":"us-east-1",
  "input.fs.prop.accessKey":"XXXXXX",
  "input.fs.prop.secretKey":"XXXXXXXXXXXXXXXX"
}
&sourceURIStr=<s3://mybucket/pinot_input_csv/transcript.csv>"

what would be the issue ?

config map string needs to be url encoded
