TLS with cerificate as a String Resource

[Mgalazka2323]

Hello,
I tried with TLSSettings and adding proper certificate as a parameter
MQTTClient(
mqttVersion = MQTTVersion.MQTT3_1_1,
address = a!!,
port = port,
userName = u,
password = p?.toByteArray()?.asUByteArray(),
cleanStart = true,
clientId = "xxxxxxxxx"
tls = TLSClientSettings(serverCertificate = crt!!)
)
the exception is generated like this: java.io.FileNotFoundException: ENAMETOOLONG (File name too long)
crt is proper certificate I think that in older version it worked but now i tried with 0.4.6, 0.4.7, 0.4.8 but without success
Can you help me with this ?
best regards
Mateusz

Hello, can you please give me the crt variable content? You can generate a new certificate in the same way to avoid sharing the one you are using.

I tried replicating the problem but I couldn't. The certificate is correctly parsed. If I change the header to corrupt the data, then I get a java.io.FileNotFoundException but not for file name too long, just incorrect path syntax, but that could be a difference of the JVM we are using to run it. Please check again that your crt variable actually contains the correct certificate value OR the path to the file containing it.

This is my code:

public fun main() {
    val ca = """-----BEGIN CERTIFICATE-----

Hello, thank you for your time ...you're right , problem was with my certificate because \n after saving was removed and certificate doesn't have proper structure.
Thank you one more time for your time and great job with this library !!
