Find yourself a JSON aware editor, such as Visual Studio Code, or Google for any online JSON viewer and get into the habit of using these tools to check your JSON.

for example, https://jsoneditoronline.org/#left=local.taxoru&right=local.hucize gives this error with your JSON:

Parse error on line 3:
...", "qrCodeData": "{"SellerGstin":"abc","
-----------------------^

remove the first " after "qrCodeData": and you should be valid.
