Hi 😁 what kind of data structure is expected by the "Run Stream" CSV Upload for e.g. the simple filter streams example? Thanks

Matt Ellis

@mellistibco

A csv file :smile: the header row maps to the field names when mapping

AndreasHeissenberger

@AHeissenberger_twitter

The stream interface has on field. Name: "input" Type: "integer" my CSV has one column with header "input" and one number per line (UTF-8, NL) and I get this error msg in the log:

@fcastill do you happen to know off the top of your head? I’m not at a computer atm otherwise would check

AndreasHeissenberger

@AHeissenberger_twitter

@mellistibco thanks for your quick reply - I got it working - the solution is to switch the stream interface into type object - this is what the Web UI "Run Stream" creates from a CSV
input
1
2
=>
{"input",1}
{"input",2}

hi i have a question, to implement a flogo trigger I can use the flogogen tool(which is mentioned in the docs) which is the old 0.5.6 version. where currently the Flogo on project-flogo github is using 0.9 version! which one should I use? and the new version 0.9 doesn't support the triggers creation

i compared the triggers from project-flogo github and TIBCO flogo github they are different their code structure is very different, the TIBCO uses flogo-lib where the project-flogo uses core, I am just curious which one should I use and if I should use the 0.9 one then how can I use that for the triggers

Matt Ellis

@mellistibco

@afarooqi8 you should be using everything inside the project-flogo org

skothari12

@skothari12

https://github.com/project-flogo/cli-plugins/tree/master/devtool . This gen tool should create trigger compatible with 0.9 + .

Asadullah Farooqi

@afarooqi8

thanks guys

Asadullah Farooqi

@afarooqi8

can you guys give me a hint how will this process take place?

I can't think of extration of vars from json events

Tracy Li

@lixingwang

Yes @afarooqi8 You can pass as data type any to handler and to flow input.

then it's your/user logic to handle any type data in flow.

Asadullah Farooqi

@afarooqi8

okay thanks :) i'll try to do that by looking at other triggers

Asadullah Farooqi

@afarooqi8

hey @skothari12 the plugin is throwing an error while installation

Failed to rewrite the flogo bin. Will need to test and perhaps see if a bug was introduced at somepoint. Will check tomorrow and update here @afarooqi8

I would make sure if the GOPATH and GOROOT are properly set.

Asadullah Farooqi

@afarooqi8

@skothari12 my go is installed at /usr/local/go/ when I run which go i get /usr/local/go/bin/go. and my GOPATH is /home/asd/go/

and GOROOT is unset, which should be goroot?

skothari12

@skothari12

what does your go env say ?

Asadullah Farooqi

@afarooqi8

I set the GOROOT path it's /usr/local/go but still

Matt Ellis

Asadullah Farooqi

@afarooqi8

flogo cli version 0.10.0

Matt Ellis

@mellistibco

hmm, seems to work for me

Asadullah Farooqi

try export GO111MODULE=on

@afarooqi8

sure

still not working :)

Matt Ellis

@mellistibco

can you try removing /home/asd/go/bin/flogo and reinstalling the cli?

perhaps a permissions issue on the /home/asd/go/bin/flogo bin?

Asadullah Farooqi

@afarooqi8

sure i did it yesterday and i'll do it again, btw I just remove the bin file and del the mod dir

Asadullah Farooqi

@afarooqi8

now i'm getting some reasonable error

hi guys @mellistibco @skothari12
i tried it on my other machine and some other machines as well

but the result is the same the text file busy error

skothari12

@skothari12

Can you try on a container ? I tried same thing and I didn’t face any issue. So there’s definetly something going on with your env. Although I just cannot narrow down the issue.

Asadullah Farooqi

@afarooqi8

i tried it on the vagrant machine,
btw how do you install the cli and the plugin?
