toJSON global helper missing when running in docker



  • I have a template that calls the global helper toJSON. This works fine when running normally. When I switch to run in a docker container (which I need to do for production, Azure environment etc) I get the following error:-
    Error occured - Error during rendering report: Error during rendering report: Missing helper: "toJSON" Stak - Error: Missing helper: "toJSON" at Object. (/usr/src/app/node_modules/handlebars/dist/cjs/handlebars/helpers/helper-missing.js:19:13) at Object.eval (eval at createFunctionContext (/usr/src/app/node_modules/handlebars/dist/cjs/handlebars/compiler/javascript-compiler.js:254:23), :6:89) at main (/usr/src/app/node_modules/handlebars/dist/cjs/handlebars/runtime.js:173:32) at ret (/usr/src/app/node_modules/handlebars/dist/cjs/handlebars/runtime.js:176:12) at ret (/usr/src/app/node_modules/handlebars/dist/cjs/handlebars/compiler/compiler.js:525:21) at /usr/src/app/node_modules/jsreport-handlebars/lib/handlebarsEngine.js:25:14 at evalmachine.:1:41 at ContextifyScript.Script.runInContext (vm.js:35:29) at ContextifyScript.Script.runInNewContext (vm.js:41:15) at Object.runInNewContext (vm.js:93:38)

    This has been working fine for many months and only started to go wrong last night. I thought it might be a docker issue so I downgraded to an earlier version that I knew was working. That made no difference so I now believe it's a JSReport issue. Any help much appreciated as I need to run some production reports in the next couple of days.



  • Hm, how do you define the toJSON helper? As an asset? Does the user which is rendering the report have permissions for it?



  • Hi Jan, yes it's an asset. I assume the user rendering the report has permissions as I'm running it and I created it. I've never set permissions before and it has always worked until now but obviously worth checking. Where do I go to check permissions? I've managed to workaround the issue by copying the function to the helper.js for each template but this is obviously not ideal.
    Thanks, Paul



  • If you log in with the user rendering the report, open studio and see the required asset, it would mean you have permissions for it.
    Can you run the template using the Debug button in the studio and paste here the output?



  • Hi Jan, yes I have permissions when running normally and when running in Docker. Here is the output from the debug button:-

    Thanks

  • Hm. Is there any chance you would be able to click in the studio settings the Export button and email me the zip so I would be able to replicate the issue?



  • Certainly, I sent them to your hotmail address. Many thanks, Paul
