Hi all,

I have an issue with Gatling typescript and grpc.

I have in protobuf folder that structure :

- protobuf
  - google
    - protobuf
      - “standards google proto files”

  - com
    - xxx
      - mobile
        - common
          - v1
            - models

            - services

            - types

exemple of proto import in models proto’s :

> syntax = “proto3”;
> 
> package com.xxx.mobile.common.v1.models;
> 
> import “com/xxx/mobile/common/v1/models/multi\_lang\_string.proto”;
> 
> import “com/xxx/mobile/common/v1/types/agreement\_acceptance\_method.proto”;  
> import “com/xxx/mobile/common/v1/types/agreement\_type.proto”;  
> import “com/xxx/mobile/common/v1/types/agreement\_show\_at.proto”;
> 
> import “google/protobuf/wrappers.proto”;
> 
> message Agreement {  
> string id = 1;
> 
> …

When I try to launch a simple simulation, gatling fails at the beginning during proto transformation

> Bundling a Gatling simulation with options:
> 
> sourcesFolder: src/simulations
> 
> protoFolder: protobuf
> 
> bundleFile: target/bundle.js  
> com/xxx/mobile/common/v1/models/multi\_lang\_string.proto: File not found.  
> com/xxx/mobile/common/v1/types/agreement\_acceptance\_method.proto: File not found.  
> com/xxx/mobile/common/v1/types/agreement\_type.proto: File not found.  
> com/xxx/mobile/common/v1/types/agreement\_show\_at.proto: File not found.  
> google/protobuf/wrappers.proto: File not found.

All theses files are actually available.

Any ideas ? is there any limitation with that complex hierarchy ?

Hi @vianneym,

We have release Gatling JS 3.15.102 with a fix for this issue. If you upgrade all the Gatling dependencies in your project, the imports between proto files should now be resolved properly. Please don’t hesitate to let us know once you have confirmed it on your use case.
