Error when running matrixPost with metrics: ['distance'] #12

Closed ghost closed 2 years ago

ghost commented 2 years ago

Hello. I'm getting the following error when doing a matrixPost with metrics different from the default ['duration'] TimeDistanceMatrix distanceMatrix = await client.matrixPost(locations: cities, metrics: ['distance'], units: 'm'); Do you have any idea why this happens? The request works OK in Postman, why is this happening in Flutter Dart? How can I fix it?

Hmmm just seems like a issue of making the list nullable. Will diagnose this in a few hours.

@Dhi13man I tried finding out what's wrong but I keep getting the same error. It doesn't make sense, the list of locations I pass isn't null, it's in correct type and everything. Tried everything. metris ['distance'] causes the problem but can't find out why. I run it again and this time the same error is thrown at a different line:

Please let me know if there is anything I could do to help you troubleshoot it, I need it fixed for my project. Thanks.

Checking now.

Please fork and test the branch 12-error-when-running-matrixpost-with-metrics-distance. The Issue should be resolved there. If everything works fine, will deploy new version with fix.
