            Getting empty ctx.body on post requests in Koajs
            Asked 2022-Apr-10 at 09:50

            I'm new to Koa. I wrote a simple api server with it. I have used "koa-bodyparser" and i have added content-type: application/json to the request header, but i still get empty request body on post requests. Could anyone please guide me?

            this is my server.js



            Answered 2022-Apr-10 at 09:50

            You are confusing ctx.body with ctx.request.body, at least in your log statement (in the destructured assignment it is actually correct).

            ctx.body is the same as ctx.response.body, it's the response body which is empty because you didn't set it yet.

            ctx.request.body is the request body which you actually want.

            Some other issues I noticed:

            • You use username and password in those ctx.assert lines before they are defined.

            • In your duplicate user case, you forgot to return from your function, so the rest of the function will still run and even with an existing user you will create a new one.

            Since you seem to be working on debugging that error 500: A little tip, error.message is quite useless for debugging as it's missing the stack (most importantly - since this is what shows you where exactly the error came from) and the error class, code and other properties. If you use console.error, always log the whole error object and not just the message: console.error(error). If you want to prepend some text, don't use concatenation, use separate arguments instead, so the object is still formatted: console.error('Error in request:', error).

            If you need a string (for example when returning it as response, which you should do only in development mode by the way because you don't want to expose your inner workings to potential attackers), use error.stack and not error.message, because it will contain a lot more information.

            Heroku Shopify Application Error 'npm ERR! ERESOLVE unable to resolve dependency tree'
            Asked 2022-Apr-03 at 07:31

            Greetings I have a problem with Heroku because it's don't want to install legacy packages for my Shopify app, my Shopify app is on Github and I just set up everything that my application needs, but when I deploy the main branch on Heroku I get this error in Heroku console below, can someone help me fix this?



            Answered 2022-Feb-10 at 13:23

            Your lock file contains conflicting dependencies. Since you were able to reproduce the error locally using npm ci we have a good way to test a fix locally.

            It looks like you are depending directly on React 16. Is that something that you need directly, or is it just a dependency for Next.js?

            If it's not something you need directly, upgrade it per the Next.js docs:

            Role is null after just creating it
            Asked 2022-Mar-12 at 22:14

            I'm writing a shadowban command right now, and this code is causing problems, even after creating the shadowban role, var role will be null.

            This is probably a really stupid error which I caused in some sort of form, but I just can't figure it out.



            Answered 2022-Mar-12 at 22:14

            The create role function returns the role that's created. Simply store that instead of attempting to fetch it from the roles list. When you create a new role, the cache is not updated until the role created event is fired, so attempting to fetch it immediately after creation will always fail.

            After generating the token you should set that token in user's browser as cookie or some other way,

            Then while requesting / page check for the token and verify the validity

            Strapi connect endpoint 500 internal server error
            Asked 2022-Feb-19 at 06:13

            I have Strapi installed on Azure VM. trying to connect to the /api/connect/microsoft endpoint to do authorization with active directory. Everything works locally but on the server it keeps giving me a 500 internal server error. Strapi on Azure vm is set up with nginx.

            This is what we found in the logs



            Answered 2022-Feb-19 at 01:56

            I am not using Stapi but the answer is in the error message:

            Error: Cannot send secure cookie over unencrypted connection

            It means that without using https, in your cookie configuration you should have:

            secure: false

            The fix is actually simple, but the reason is hard to find.

            async middleware must either call await next() or return next() at the end. Otherwise a 404 error is caused.

            Adding await next() to the async /login-success callback, fixed the issue.

            Answered 2022-Jan-15 at 23:03

            You don't need to add an extra parameter. app.use wants a function as first parameter. So, you can create a function that returns the desired function to use in app.use.

            You don't need to manually put $and as by default all conditions are matched. Also you misspelled someshop as shomeshop in document 2, that might be one of the reasons of getting an empty array. You also don't need to use .* in RegExp("/.*" + searchQuery + ".*/") as by default if the text matches any part of the input, the regex will return true and captures the first match. Passing a regex with the operator $regex is also unnecessary. My advice is using searchQuery.replace(/\s+/g, ' ') instead. The example below should work.
