Internal tool error

Sometimes the third-party libraries that APIBlocks uses will thow errors that we didn't expect. In this case you will receive an Internal tool error.

The data field of the Internal tool error has a standard schema. See an example response below:

"jsonrpc": "2.0",
    "id": "15ab1a33-2991-4992-9eda-dca939f99709",
    "result": {
        "dna": {
            "seq": "TGGCTTACGAGCTAC"
    "error": {
        "code": 1,
        "message": "Internal tool error",
        "data": {
            "method": "ThirdPartyClass.optimize",
            "exception": "Optimisation failed to converge"
