XMLHttpRequest error while using http post flutter web

[deniscass]

Describe the bug

I`m attempt use a self installed typesense server to get better search in my Flutter web project. Is a simple personal project to start learning about typesense. But i get issues to get server access in my flutter web lcoalhost develop machine. with a generic error:

XMLHttpRequest error in search and crud operations to add content to index search. I`m using Postman client to test my server and all wordks fine, but in Flutter web no. I check api keys, SSL cert with Letsencrypt certificate, and no work.

I attempt use enable-cors and disable it too, but no working too.

Some tips to get search and upsert functions working?

Thanks in advance

Steps to reproduce the behavior:

1. Follow steps in pub.dev/typesense
2. Install typesense-serve in Ubuntu server linux
3. Setup a new flutter project
4. Atempt start search or add data to typesense from flutter web

Hello @deniscass Did you use this guide to install typesense? https://typesense.org/docs/guide/install-typesense.html#deb-package-on-ubuntu-debian

You will have to enable CORS typesense instance https://typesense.org/docs/26.0/api/server-configuration.html#cors

Hi Harpreet, Thanks in advance for help-me. I use this same guide. I enable CORS and set cors-domains to * and enable Lets encrypt ssl. With postman and curl works fine and very fast. Great features from TypeSense over ElasticSearch.

I try api-key and can request all actions, for example, from Postman and Curl , i can:

• create my collections
• Insert and update documents
• Drop collection and create again
• Test my search filters.

But in my Flutter web app no work nothing. I debut until underground functions in dart SDK that create and send requests and validade all parameters, security, ssl and body content and no issues, but HTTP Response is same XMLHttpRequest.

https://github.com/typesense/typesense-dart/issues/116#issuecomment-1113516045 This user also had the same issue and he said it worked fine with direct HTTP call https://pub.dev/packages/http#using Could you try if this works for you also? I can then take a closer look into the package itself.
