[Cogni Tinto]

Hi All! Wish you all a Happy New Year 2025!

Can anyone let me know how to solve this -

Am trying to upload a  sample HL7v2 message to  HL7v2 store - 

Option 1 - Text format:

hl7_message2.txt file -

Hello,

These are the errors that I could see:

1. Carriage return should be \r, not \n

2. The input file is supposed to be a message proto with base64 encoding of the data field.

Please refer to this guide on how to replace \n with \r and perform base64 encoding.

So the expected curl command is:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     --data @message_file.txt \
     "https://healthcare.googleapis.com/v1/projects/${PROJECT?}/locations/${LOCATION?}/datasets/${DATASET?}/hl7V2Stores/${HL7_STORE?}/messages"

where message_file.txt has the following format:

{"message": {"data": "base64-encoding-of-the-raw-message"}}

Best,
