String interpolation in Chainlink TOML jobspecs

I’ve got a HTTP POST task that’s sending a lump of JSON to the GraphQL External Adapter.

When I send a literal regular JSON string it works fine.

{\"jobRunId\":1,\"data\":{\"query\":\"query rightToLeft ($code: ID!) {language(code: $code) { rtl }}\",\"variables\":{\"code\":\"ar\"},\"graphqlEndpoint\":\"https://countries.trevorblades.com/\"}}

When I replace {\"code\":\"ar\"} with {\"code\":\"$(decode_cbor.languageCode)\"} I get the following error when the HTTP POST task is executed

requestData: while unmarshalling JSON: invalid character '_' after object key:value pair; js: {"jobRunId":1,"data":{"query":"query rightToLeft ($code: ID!) {language(code: $code) { rtl }}","variables":{"code":"{ "__chainlink_key_path__": "decode_cbor.languageCode" }"},"graphqlEndpoint":"https://countries.trevorblades.com/"}}: bad input for task

I’m trying to use the $(foo) notation that’s documented here https://docs.chain.link/docs/jobs/task-types/http/

Here’s the complete jobspec’s observationSource:

    decode_log   [type="ethabidecodelog"                   abi="OracleRequest(bytes32 indexed specId, address requester, bytes32 requestId, uint256 payment, address callbackAddr, bytes4 callbackFunctionId, uint256 cancelExpiration, uint256 dataVersion, bytes data)"                   data="$(jobRun.logData)"                   topics="$(jobRun.logTopics)"]      decode_cbor  [type="cborparse" data="$(decode_log.data)"]     post         [type="http" method=POST url="https://ea-graphql-k3zq5wb52q-uc.a.run.app/" requestData="{\"jobRunId\":1,\"data\":{\"query\":\"query rightToLeft ($code: ID!) {language(code: $code) { rtl }}\",\"variables\":{\"code\":\"$(decode_cbor.languageCode)\"},\"graphqlEndpoint\":\"https://countries.trevorblades.com/\"}}"]      parse        [type="jsonparse" path="result,data,language,rtl" data="$(post)"]     encode_data  [type="ethabiencode" abi="(bool value)" data="{ \"value\": $(parse) }"]     encode_tx    [type="ethabiencode"                   abi="fulfillOracleRequest(bytes32 requestId, uint256 payment, address callbackAddress, bytes4 callbackFunctionId, uint256 expiration, bytes32 data)"                   data="{\"requestId\": $(decode_log.requestId), \"payment\": $(decode_log.payment), \"callbackAddress\": $(decode_log.callbackAddr), \"callbackFunctionId\": $(decode_log.callbackFunctionId), \"expiration\": $(decode_log.cancelExpiration), \"data\": $(encode_data)}"                  ]     submit_tx    [type="ethtx" to="0x188b71C9d27cDeE01B9b0dfF5C1aff62E8D6F434" data="$(encode_tx)"]      decode_log -> decode_cbor -> post -> parse -> encode_data -> encode_tx -> submit_tx

What am I doing wrong?

Any help is kindly appreciated.

How do I calculate number of multiplication, exponential, and pairing operations in a cryptographic algorithm (signcryption/unsigncryption)?

I have been working on signcryption scheme and its security proof. I want to compute the efficiency in terms of number of scalar multiplication operation, number of exponential operations, and number of bilinear pairing operation. I am comparing it with other schemes as well. I think I am missing out some information regarding point scalar ::Listen

I have been working on signcryption scheme and its security proof. I want to compute the efficiency in terms of number of scalar multiplication operation, number of exponential operations, and number of bilinear pairing operation. I am comparing it with other schemes as well. I think I am missing out some information regarding point scalar multiplication and couldn’t figure how should I count the number of multiplication operation. For example if U in the figure below, I see only 2 multiplication operations U1=r1P2 and U2=r1QA. Is it correct?
