Question

build command error - cannot use engine.DirectRunner

akpuvvada opened this issue 5 years ago · comments

I am trying to follow steps in https://tibcosoftware.github.io/flogo/faas/how-to/ to try Flogo.
When I try to run Flogo Build command, I am getting below error. Please help me understand how to resolve this. I am using the same JSON as given in the page.

After this gets merged you can do flogo update github.com/project-flogo/core@master . And one more thing. it should be flogo build -e --shim aws_lambda_trigger("id" of the trigger) . It should be changed in the doc too.

Thanks, Samip.

When is this expected to merge or is it already merged? How do I know?

Samip Kothari · Answer 3 · Sat Nov 16 2019 01:47:32 GMT+0800 (China Standard Time)

It's merged.

Still not working. Now I am getting new error.

Did you run flogo update github.com/project-flogo/core@master ?

A. K. Puvvada · Answer 6 · Sat Nov 16 2019 04:30:13 GMT+0800 (China Standard Time)

Did you run flogo update github.com/project-flogo/core@master ?

Yes, I did and it was successful.

Hmm. I am not facing that issue. Can you try recreating the project and updating the core again?

I deleted the myapp folder and tried again. Below is the complete log

You didn't do flogo update github.com/project-flogo/core@master . But something's going on here that I don't understand. You shouldn't be getting

.\shim.go:30:6: main redeclared in this block
        previous declaration at .\main.go:22:6
...

I tried the same thing and it worked for me. I would suggest try installing flogo-cli again. If it doesn't work, Can you zip up myApp folder and share it ?

A. K. Puvvada · Answer 11 · Tue Nov 19 2019 00:55:34 GMT+0800 (China Standard Time)

I reinstalled the CLI and tried again.
Still getting error. Please help. Below please find complete command history with console output/errors.

Alright. So this issue does show up in windows. Let me work on it and I'll keep you posted.

Hi Samip, Is this going to take time?

Samip Kothari · Answer 15 · Thu Nov 21 2019 03:29:37 GMT+0800 (China Standard Time)

I have updated the cli with the patch. The thing is you should have the zip which you can upload to AWS in the src . It's only giving error because of other reasons. The complete solution will be added in couple of days after review.

A. K. Puvvada · Answer 16 · Thu Nov 21 2019 03:51:04 GMT+0800 (China Standard Time)

Thanks for the update. Let me know when ready. I found the zip file created.

A. K. Puvvada · Answer 17 · Thu Nov 21 2019 04:37:36 GMT+0800 (China Standard Time)

That zip file is empty. There is no files in it. I was not able to test it as I don't have permission to deploy in AWS - checking with support.
Is that expected that the zip file is empty?

Samip Kothari · Answer 18 · Thu Nov 21 2019 04:46:36 GMT+0800 (China Standard Time)

You mean the zip file is of 0 mb size?

A. K. Puvvada · Answer 19 · Thu Nov 21 2019 04:57:01 GMT+0800 (China Standard Time)

Size says 1 KB and when I open it in 7zip, I don't see any files in it.
Also, when I unzip the file, I get an empty folder.

Samip Kothari · Answer 20 · Thu Nov 21 2019 05:44:43 GMT+0800 (China Standard Time)

Well the zip is the compressed version of the binary. It is not suppose to contain any files. I would suggest updating the cli and running the build again. The binary name handler should be created and must be of atleast 10 mb .

A. K. Puvvada · Answer 21 · Fri Nov 22 2019 00:36:21 GMT+0800 (China Standard Time)

I have seen sample handler.zip files worked on by my colleagues in older version of Flogo which have files. I am still following-up on permission to create lambda function in AWS. Yet to test uploading/deploying.

Hi @skothari-tibco any update on this issue?

Samip Kothari · Answer 23 · Tue Nov 26 2019 00:56:05 GMT+0800 (China Standard Time)

Yes. The CLI has been updated. So if you would update the CLI and the core version, the demo will work on the Lambda. But let me know if you have any issues.

What's the flogo cli version ?

A. K. Puvvada · Answer 26 · Tue Nov 26 2019 05:02:26 GMT+0800 (China Standard Time)

flogo cli version 0.9.1-rc.2-2-g67f15b4

Samip Kothari · Answer 27 · Tue Nov 26 2019 05:05:33 GMT+0800 (China Standard Time)

Yeah... that needs to be updated.

A. K. Puvvada · Answer 28 · Tue Nov 26 2019 05:06:33 GMT+0800 (China Standard Time)

I reinstalled the CLI this morning. Thought that will fetch latest version. How do I update it?

Samip Kothari · Answer 29 · Tue Nov 26 2019 05:33:47 GMT+0800 (China Standard Time)

Can you try it again? It should say 0.9.1-rc.3 .

Samip Kothari · Answer 30 · Thu Nov 28 2019 03:23:33 GMT+0800 (China Standard Time)

I'm guessing this worked right?

Yes, Samip. Thanks.
