Hello, I’m always getting this error and I cannot can around it; I get this error only when the I have something in the encoded array; with empty array the function works perfectly.
Can someone help me here?

Call was rejected:

this is my candid:

service: () -> {
    derivation_origin: (record {frontend_hostname:text}) -> (variant {Ok:record {origin:text}; Err:variant {Internal:text; UnsupportedOrigin:text}});
    get_credential: (record {signed_id_alias:record {credential_jws:text}; prepared_context:opt vec nat8; credential_spec:record {arguments:opt vec record {text; variant {Int:int32; String:text}}; credential_type:text}}) -> (record {Ok:record {vc_jws:text}; Err:variant {Internal:text; SignatureNotFound:text; InvalidIdAlias:text; UnauthorizedSubject:text; UnknownSubject:text; UnsupportedCredentialSpec:text}}) query;
    prepare_credential: (record {signed_id_alias:record {credential_jws:text}; credential_spec:record {arguments:opt vec record {text; variant {Int:int32; String:text}}; credential_type:text}}) -> (variant {Ok:record {prepared_context:opt vec nat8}; Err:variant {Internal:text; SignatureNotFound:text; InvalidIdAlias:text; UnauthorizedSubject:text; UnknownSubject:text; UnsupportedCredentialSpec:text}});
    vc_consent_message: (record {preferences:record {language:text}; credential_spec:record {arguments:opt vec record {text; variant {Int:int32; String:text}}; credential_type:text}}) -> (variant {Ok:record {consent_message:text; language:text}; Err:variant {GenericError:record {description:text; error_code:nat}; UnsupportedCanisterCall:record {description:text}; ConsentMessageUnavailable:record {description:text}}});
}

Here is the Azle/Typescrit:

  @update(
    [PrepareCredentialRequest],
    IDL.Variant({
      Ok: PreparedCredentialData,
      Err: AzleIssueCredentialErrorType,
    }),
  )
  prepare_credential(request: PrepareCredentialRequestType): { Ok: PreparedCredentialDataType } | { Err: IssueCredentialError } {
    const credentialJws = request.signed_id_alias.credential_jws;
    console.log({ credentialJws });
    const response = new TextEncoder().encode(request.signed_id_alias.credential_jws);
  
    return {
      Ok: {
        prepared_context: response
      },
    };
  }

CC @lastmjs since this is about Azle

Did you ask about this in the Discord?

Try reading the debugging section of The Azle Book: Debugging - The Azle Book

Please track down exactly where it is breaking by using the debugging techniques described in the book (basically console.log and try/catch everywhere).

I’m guessing you have designed one of your IDL types incorrectly.

I tacked it; one of the returned value was incorrect
