Samip Kothari

@skothari-tibco

Looks like an error with github.com/shirou/gopsutil library.

There are two flows in my application, when I build them individually they build for windows , when building both gives me this error

Samip Kothari

@skothari-tibco

Hmm; I’m able to build it without error. Getting error while running though

With the announced support by TIBCO for Apache Pulsar i’ve added a new publisher activity to Flogo OSS. Activity can be found here: https://github.com/mmussett/flogo-components/tree/master/activity/pulsar
Will start on Pulsar Trigger this week.

Hai i am working on mqtt activity when i run the application im getting the following error

Failed to create engine: error unmarshalling flow: Network Error : %!s(<nil>)

Could any one help me what is the reason of getting this error

Samip Kothari

@skothari-tibco

Is your mqtt queue reachable? and whether is it calling the right url?

I'm trying to compile from github and I can have 'yarn start server' working properly. However, 'yarn start client' gives an error it's too old. I do a 'yarn upgrade' and each time I get
yarn start client
yarn run v1.16.0
$ ng serve client
An unhandled exception occurred: Cannot find module 'core-js/modules/es6.regexp.split'
See "C:\Users\plavoie\AppData\Local\Temp\ng-uhr9Ux\angular-errors.log" for further details.

Anyone else is getting this ?

How do I connect to PostgreSQL ? I keep getting Failed to create engine: error unmarshalling flow: value 'postgres' is not valid when I execute it. However, the dbType, and datasourcename seem ok. Anything special I need to do ?

philippe-lavoie

@philippe-lavoie

I tried with Mysql and the same thing happen, Failed to create engine: error unmarshalling flow: sql: unknown driver "mysql" (forgotten import?)

How do I add an import as part of the build ?

Matt Ellis

@mellistibco

for postgres looks like a typo in the metadata, try postres

as for importing, i think you’ll need to edit the imports.go file

in your project dir/src @fm-tibco

philippe-lavoie

@philippe-lavoie

I'm using the docker version, can I bind the src folder somewhere ?

if you look above, I can't get flogo-web to work locally, alwasy getting the es6.regexp.split error

Matt Ellis

@mellistibco

hmm @fcastill

Fabián Castillo

@fcastill

the engine project is located under /flogo-web/local/engines/flogo-web in the docker image, I guess you could enter a running container using docker exec -it /bin/bash and navigating to that folder to modify the src or you can mount that directory too

there’s no way to refresh the UI to take any manual changes you did to underlying engine project though, if you install new contributions you will need to re-start the server app

Fabián Castillo

@fcastill

@philippe-lavoie about the issues running the web app locally please make sure you have nodeJS v10 or later, it might also be an issue with outdated dependencies, make sure they’re up to date by running yarn install inside the flogo-web project. In your case since you upgraded yarn I think it is better to delete the node_modules directory and then run yarn install

philippe-lavoie

@philippe-lavoie

would nodeJS 11 be a problem ? Although I though since the server works correctly

Fabián Castillo

@fcastill

just tried Node v11.15.0 and yarn 1.16.0 and client app is running without issues

philippe-lavoie

@philippe-lavoie

I'm deleting node_modules

still need another 14 minutes...

the joy of node programming...

I'm writing a flogo library that starts up a UDP server, which will be used for both trigger and activities. The challenge is that this is intended to be a shared service, so is there a mechanism in Flogo that allows an existing handle to be passed to another activity?

Samip Kothari

@skothari-tibco

Yes. You can use something which is called connections. You edit the UDP trigger to accept connections; you define that in the app.json and access that in any of the activity. Eg. https://github.com/project-flogo/datastore-contrib/tree/master/mongodb . https://github.com/skothari-tibco/samplekafkaconn .

@skothari-tibco Thanks.

What is the advice, should we be using github.com/TIBCOSoftware/flogo-lib/core/ or github.com/project-flogo/core?
