Error 503 When requesting REST API endpoints

[gabrielbenavidez]

Hi,
I'm having some trouble getting my ePAD lite server started and I would really appreciate some feedback as to what may be causing the issues as well as how I may go about resolving it.

My issue seems to be similar if not the same as issue number 5 from https://github.com/RubinLab/epad-dist/issues/26#issuecomment-959420948

Environment

WSL Ubuntu (20.04.1)
Latest epad-dist version

Steps to reproduce

1. Clone epad-dist repo: git clone https://github.com/RubinLab/epad-dist.git
2. Generate epad_lite_dist directory and files: ./configure_epad.sh ../epad_lite_dist ./epad.yml
3. Start all containers: docker-compose up

Errors

1. mariaDB

Error
Access denied for user 'admin'@'localhost' (using password: YES)

Fix

• Create mariadb user "admin" in epad_mariadb container: CREATE USER 'admin'@'localhost' IDENTIFIED BY 'manager'
• Grant admin user permissions: GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost'; FLUSH PRIVELEGES;

2. epad_lite

Error
"Cannot connect to mariadb (err:afterDBReady. Error: Lite2thick data migration. Error: Cannot parse '( )': Encountered \" \")\" \") \"\" at line 1, column 2.\nWas expecting one of:\n <NOT> ...\n \"+\" ...\n \"-\" ...\n <BAREOPER> ...\n \"(\" ...\n \"*\" ...\n <QUOTED> ...\n <TERM> ...\n <PREFIXTERM> ...\n <WILDTERM> ...\n <REGEXPTERM> ...\n \"[\" ...\n \"{\" ...\n <NUMBER> ...\n <TERM> ...\n \"*\" ...\n ), shutting down the server"}

Fix
N/A: Not sure if this error has any significance.

3. epad_js

Error
"GET /api/users/admin HTTP/1.1" 503 80 "http://localhost/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.99 Safari/537.36" "

Fix
If REACT_APP_API_URL environmental variable in the docker-compose.yml file is changed from http://localhost/api to http://localhost then the request request doesn't fail and returns a 200 OK.

So far this only fixes the login error but I'm still not able to perform any other tasks such as uploading DCM files.

Thank you in advance

Hi Gabriel, would you try the mariadb image with the tag 20200308 <https://hub.docker.com/layers/rubinlab/mariadb/20200308/images/sha256-6785309e2fb510ec5cdc4f65e2043417715039bf4ebd12ebe5a5ff7b18ed59a7?context=explore>, rubinlab/mariadb:20200308. You will need to edit it in docker-compose.yml file which is in your epad_lite_dist folder. After that please run the commands below; 1.docker-compose down 2. docker-compose build --no-cache mymariadb 3. docker-compose up -d to run the commands above you need to be in your epad_lite_dist folder. Please let me know how it goes. We can do it together. Best Regards

Thank you @acavit I'll try your suggestion and let you know if it resolved the issue. If I'm still getting errors maybe we can look at it together as you said.

@acavit Thank you for the suggestion, I updated the docker-compose.yml file to use the rubinlab/mariadb:20200308 image. This resolved the first error I was getting from the mariadb container stating: Access denied for user 'admin'@'localhost' (using password: YES). I performed steps 1 and 3 from your suggestion and skipped step 2 because the docker-compose.yml is set to use an image rather than build an image from mariadb/Dockerfile. I still seem to be getting the second and third error in my original post which is the epad_lite container cannot connect to mariadb, and the epad_js container is returning a 503 for API requests. Please let me know if you have any suggestions as how I can resolve the epad_lite to mariadb connection issue. I am also available to video chat sometime soon if we're still having trouble resolving the errors.
Thank you again.

Hi Gabriel, you are welcome. If I am not wrong you set localhost as the server name for epad. Am I right ? If it is the case please change it to a valid hostname or a valid ip. You can test the validity by pinging the name/ip (ping ip or ping hostname) . Please don't use localhost or 127.0.0.1 . Let me know please if this doesn't work we can set a zoom meeting. Regards.

@acavit After trying your last suggestion I'm still having trouble getting the ePAD server running properly. I changed the host parameter in the epad.yml file from "localhost" to my actual IP address and regenerated the epad_lite_dist directory. I also tried adding a hostname to my etc/hosts file called "indiana" (which points to my IP address) and using that hostname. Could you please clarify if this is along the lines of what you suggested in your last message.

Note: I also tried using the "thick" mode and changing epadlite and epadjs to use tag v0.5 instead of master as suggested from a closed issue thread for this repo by a user who get their ePAD server working making these changes, but I didn't have much luck with this.

Here's a Gist link to my docker-compose.yml file incase it can be of help:
