ISR not in IRAM!

I hope I'm not breaking protocol here, but I'm a bit of a noob. After looking at some different projects, I thought this one looked like what I wanted, so I had 20 boards printed up at JLC PCB and am trying to get them up and running. I wasn't able to do it in PlatformIO, mostly because I couldn't get PubSubClient to work. So I brought it over to Arduino IDE. I got it to load (although I had to roll JSON back), but when I restart it, I get the following on the Serial Monitor:

........... WiFi connected IP address: 192.168.1.187 Attempting MQTT connection...Connected ISR not in IRAM!

Any ideas how to solve this? I'd like to start using these things! Thanks, Chip

Gosh - I'm really sorry but I have not touched this project for about 5 years now. It really was, as I stated in the Readme:

"This is all still very much a work in progress. I have built a prototype board and have had it running on my desk but the results leave me rather confused :-("

As I recall there were some bugs in the PCB layout design too; it really was very much a prototype. i.e. things like the variable resistor should be replaced by a fixed one and most of the test points removed etc...

Having said all that it did "work" to a fashion on my desk in a pot but I never got any further than that, sorry.

Thanks for your quick reply. Looks like the only problem I can see now is due to the changes from json 5 to 6. Unfortunately, I'm a beginner with PlatformIO and not familiar with json. I think I was able to upgrade the first two json lines using the json upgrade guide, but can't figure out the others. I'll post the errors below. I'd greatly appreciate any help you could provide, and I'm sure others would benefit from a GitHub update.

BTW, I noticed you discussed PCB water ingress and water proofing elsewhere online. If you're interested, I'm comparing Liquid Tape, FlexSeal Clear, PlastiDip and perhaps silicone and/or urethane conformal coatings and can let you know the results.

Thanks Chip

Oh, and let me know if you want me to send you some seeds from my Cajun Belle and Fish pepper plants. The later is a very interesting African-American heirloom from the Philadelphia/Baltimore region with beautiful variegated leaves and fruit and Caribbean flavor and heat.
