BeginMultiPathStream

[Amey112]

'mBeginMultiPathStream' was not declared in this scope { "resource": "/platformIO/SmartBoard-Arduino/.pio/libdeps/esp32dev/Firebase ESP32 Client/src/Firebase.h", "owner": "cpp", "severity": 8, "message": "'mBeginMultiPathStream' was not declared in this scope", "startLineNumber": 1868, "startColumn": 131, "endLineNumber": 1868, "endColumn": 131 }

Expected behavior The stream is supposed to be started, rather a compilation message occurs.

IDE and its version:

• PlatformIO
• Version Core 5.2.0

Firebase ESP32 Client

• Version 3.11.3

Additional context There is also a bug in FirebaseConfig config, which prevents me from using cofig.database_url and config.signer.tokens.legacy_token

The line of code which produces the error

if (!Firebase.beginMultiPathStream(fbdo1, parentPath, childPath, childPathSize)) { Serial.println("------------------------------------"); Serial.println("Can't begin stream connection..."); Serial.println("REASON: " + fbdo1.errorReason()); Serial.println("------------------------------------"); Serial.println(); }

I don't know how you install the library but it's not correct.

You should use Library Manager in PIO Home -> Libraries and search for the library then click the blue button "Add to Project" and select the project to add.

You can also install via Library Manager CLI. https://docs.platformio.org/en/latest/core/userguide/lib/cmd_install.html https://docs.platformio.org/en/latest/core/userguide/lib/cmd_uninstall.html

I did the exact same thing.

[mobizt]

Uninstall first.

This is the Github action that used for compile and build the examples using PlatformIO on Linux for test. https://github.com/mobizt/Firebase-ESP32/runs/3650252027?check_suite_focus=true

Ok, I don't know if I being a real idiot here, but the build link is for a version released 6 days ago, and the latest version on platformio is 3.11.3 i.e. one which was released 26 days ago. Am I right here?

I have found the possible error that when you use the old API of older version library which accepts 4 arguments.

The version you're trying to install has the breaking changes in APIs since version 3.11.0.

Please refer to the new function usage which accepts 2 aruments. https://github.com/mobizt/Firebase-ESP32/blob/58410a61afab2dfd89aea45cad6b963cb5988c62/examples/DataChangesListener/MultiPath/MultiPath.ino#L134

No matter the version is, the breaking changes since 3.11.0.

Thanks, will do it, also can you check if one can download version 3.11.6 from platformio since I am only able to download version 3.11.3 and below, even though the release notes mention 3.11.6

There's an issue on PlatformIO Library Manager system since this library was added to PIO registry by the PlatformIO bot.

When I add library.json file to the repos since v3.11.4, that causes no updates in Library Manager and stuck at v3.11.3.

I will remove this library.json file from repos to fix the PlatformIO update issue.

[mobizt]

I will update the library soon (in an hour) to fix registry issue. The PIO Library Manager may update in 24 hours later.

[mobizt]

The library updated to v3.11.7.

To install it now, use

pio lib -g install  https://github.com/mobizt/Firebase-ESP32.git
