Hi, i'm using custom UI - react. i have supertokens core installed in local. used 'supertokens start' to run it. when i ping curl http://localhost:3567/hello i'm getting reply hello, but in the app when i try to http://localhost:3001/auth/signup, it shows 500 status code on sign up endpoint and also tried in postman it's throwing error as TypeError: fetch failed at Object.fetch (node:internal/deps/undici/undici:11372:11) at processTicksAndRejections (node:internal/process/task_queues:95:5) at sendRequestHelper._a (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\querier.js:51:36) at Querier.sendRequestHelper (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\querier.js:326:32) at Querier.getAPIVersion (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\querier.js:41:38) at sendRequestHelper._a (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\querier.js:177:38) at Querier.sendRequestHelper (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\querier.js:326:32) at Querier.sendGetRequest (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\querier.js:173:40) at Object.listUsersByAccountInfo (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\recipe\accountlinking\recipeImplementation.js:161:26) at Recipe.isSignInUpAllowedHelper (C:\Users\gouta\supertokens-customapp\backend\node_modules\supertokens-node\lib\build\recipe\accountlinking\recipe.js:280:25) supertokens core is running as you can see in the image. if anyone facing same issue and got it resolved kindly share the solution.

hey @gsj this is usually cause the backend process you have isn't able to connect to the core cause of firewall settings

so what should i do to resolve this? can you share some steps?

Depends on your operating system. Not sure, since this is outside the scope of a supertokens issue.

i tried docker. it's only running in-memory not connecting to MySQL DB which is in local even if i use MySQL connection details like this docker run -p 3567:3567 --network=host -e MYSQL_CONNECTION_URI="mysql://root:root@localhost:3306/supertokens" -d registry.supertokens.io/supertokens/supertokens-mysql

you should use docker compose

i want to self hosted core

And you can’t use localhost cause that points to in the docker container

i want to use self hosted supertokens core or docker to connect to my MySQL DB so that all data can be stored in my own DB. how to do that? I'm testing in local for now probably move to could if everything works fine.

can i see the docker logs from the supertokens container?

here is the log for MySQL DB

it does say that it has connected to the mysql db

There is nothing in DB and also in postman it says email already exists

r u checking the right db? Im not sure about your setup

i have only one supertokens DB in local setup. i have also checked in MySQL workbench. it shows no data but earlier when i first tried with Prebuilt UI Setup it was storing data to MySQL DB in my local machine. that why i proceeded with custom UI setup.

using pre built ot custom UI has nothing to do with db connection

Yes if it is the case then it should store the user data to the DB right? but when the i stop the supertokens core or the docker container data is wiped out.

can you delete all the tables from the mysql and restart the core? Does it recreate all the tables?

Yesturday i did that. deleted everything and started the core but it didn't do any changes to the DB, no tables were created but i was able to create user, login the user and also accessed the user management dashboard.

can you try again and show the logs of the core when it starts?

okay, i will delete all the tables and start the supertokens core again. steps i'll be doing: delete the tables in supertokens database use docker compose up -d to run the core that's it right?

yea, and make sure that the db has persistrant storage

sure. one more thing i wanted ask, is it possible to create a react + typescipt guide or example app with custom UI setup with all the features implemented so that i will be helpful.

we might do it when we have time 🙂

without docker i need to install core locally and run it right?

i mean try without docker compose

sure thanks

so if it created the tables, it means that it connected to the db successfully

but when i tried to create user it's throwing error. why is that?

the backend is not able to connect to the core

if you say so when i use docker compose there is no issue. everything is running fine. this error is thrown only when is use local supertoken core with MySQL.
